World leaders ratcheted up pressure Sunday on Russia for its war against Ukraine, with Ukrainian President Volodymyr Zelenskyy at the center of a swirl of diplomacy on the final day of the Group of Seven summit of rich-world democracies. Zelenskyy's in-person attendance at one of the world's premier diplomatic gatherings is meant to galvanize attention on his nation's 15-month fight against Russia. Even before he landed Saturday on a French plane, the G7 nations had unveiled a slew of new sanctions and other measures meant to punish Moscow and hamper its war-fighting abilities. Ukraine is the overwhelming focus of the summit, but the leaders of Japan, the United States, the United Kingdom, France, Germany, Canada and Italy, as well as the European Union, are also working to address global worries over climate change, AI, poverty, economic instability and nuclear proliferation.

Japanese Prime Minister Fumio Kishida and South Korean President Yoon Suk Yeol visited a memorial to Korean victims, many of them slave laborers, of the Aug. 6, 1945, atomic bombing. Washington wants the two neighbors, both of which are liberal democracies and bulwarks of U.S. power in the region, to stand together on a host of issues, including rising aggression from China, North Korea and Russia. Bolstering international support is a key priority as Ukraine prepares for what's seen as a major push to take back territory seized by Russia in the war that began in February last year. Zelenskyy's visit to the G7 summit closely followed the United States agreeing to allow training on potent American-made fighter jets, which lays the groundwork for their eventual transfer to Ukraine.

Security and enhanced cooperation for our victory. Peace will become closer today," Zelenskyy tweeted after his arrival. U.S. national security adviser Jake Sullivan said that President Joe Biden and Zelenskyy would have direct engagement at the summit. On Friday, Biden announced his support for training Ukrainian pilots on U.S.-made F-16 fighter jets, a precursor to eventually providing those aircraft to Ukraine. "It is necessary to improve (Ukraine's) air defense capabilities, including the training of our pilots," Zelenskyy wrote on his official Telegram channel after meeting Italian Premier Giorgia Meloni, one of a number of leaders he talked to. Zelenskyy also met on the sidelines of the summit with Indian Prime Minister Narendra Modi, their first face-to-face talks since the war, and briefed him on Ukraine's peace plan, which calls for the withdrawal of Russian troops from the country before any negotiations. India, the world's largest democracy, has avoided outright condemnation of Russia's invasion. While India maintains close ties with the United States and its Western allies, it is also a major buyer of Russian arms and oil. Summits like the G7 are a chance for leaders to put pressure on one another to align or redouble their diplomatic efforts, according to Matthew Goodman, an economics expert at the Center for Strategic and International Studies think tank in Washington. "Zelenskyy's presence puts some pressure on G7 leaders to deliver more — or explain to him directly why they can't," he said. Russian Foreign Minister Sergey Lavrov criticized the G7 summit for aiming to isolate both China and Russia. "The task has been set loudly and openly: to defeat Russia on the battlefield, but not to stop there, but to eliminate it as a geopolitical competitor. As a matter of fact, any other country that claims some kind of independent place in the world alignment will also be to suppress a competitor. Look at the decisions that are now being discussed and adopted in Hiroshima, at the G7 summit, and which are aimed at the double containment of Russia and China," he said. The G7, however, has vowed to intensify the pressure. "Russia's brutal war of aggression represents a threat to the whole world in breach of fundamental norms, rules and principles of the international community. We reaffirm our unwavering support for Ukraine for as long as it takes to bring a comprehensive, just and lasting peace," the group said in a statement. Another major focus of the meetings was China, the world's No. 2 economy. There is increasing anxiety that Beijing, which has been steadily building up its nuclear weapons program, could try to seize Taiwan by force, sparking a wider conflict. China claims the self-governing island as its own and regularly sends ships and warplanes near it. The G7 said they did not want to harm China and were seeking "constructive and stable relations" with Beijing, "recognizing the importance of engaging candidly with and expressing our concerns directly to China." They also urged China to pressure Russia to end the war in Ukraine and "support a comprehensive, just and lasting peace." China's Foreign Ministry said that "gone are the days when a handful of Western countries can just willfully meddle in other countries' internal affairs and manipulate global affairs. We urge G7 members to ... focus on addressing the various issues they have at home, stop ganging up to form exclusive blocs, stop containing and bludgeoning other countries." The G7 also warned North Korea, which has been testing missiles at a torrid pace, to completely abandon its nuclear bomb ambitions, "including any further nuclear tests or launches that use ballistic missile technology," the leaders' statement said. The green light on F-16 training is the latest shift by the Biden administration as it moves to arm Ukraine with more advanced and lethal weaponry, following earlier decisions to send rocket launcher systems and Abrams tanks. The United States has insisted that it is sending weapons to Ukraine to defend itself and has discouraged attacks by Ukraine into Russian territory. "We've reached a moment where it is time to look down the road again to say what is Ukraine going to need as part of a future force, to be able to deter and defend against Russian aggression as we go forward," Sullivan said. Biden's decisions on when, how many, and who will provide the fourth-generation F-16 fighter jets will be made in the months ahead while the training is underway, Biden told leaders. The G7 leaders have rolled out a new wave of global sanctions on Moscow as well as plans to enhance the effectiveness of existing financial penalties meant to constrain President Vladimir Putin's war effort. Russia is now the most-sanctioned country in the world, but there are questions about the effectiveness. Russia had participated in some summits with the other seven countries before being removed from the then-Group of Eight after its 2014 annexation of Crimea. The latest sanctions aimed at Russia include tighter restrictions on already-sanctioned people and firms involved in the war effort. More than 125 individuals and organizations across 20 countries have been hit with U.S. sanctions. Kishida has twice taken leaders to visit to a peace park dedicated to the tens of thousands who died in the world's first wartime atomic bomb detonation. Kishida, who represents Hiroshima in parliament, wants nuclear disarmament to be a major focus of discussions. The G7 leaders also discussed efforts to strengthen the global economy and address rising prices that are squeezing families and government budgets around the world, particularly in developing countries in Africa, Asia and Latin America. The group reiterated its aim to pull together up to $600 billion in financing for the G7's global infrastructure development initiative, which is meant to offer countries an alternative to China's investment dollars.

The U.S. has begun an aggressive new push to inflict pain on Russia’s economy and specifically its oligarchs with the intent of thwarting the Kremlin’s invasion of Ukraine. From the Treasury Department to the Justice Department, U.S. officials will focus on efforts to legally liquidate the property of Russian oligarchs, expand financial penalties on those who facilitate the evasion of sanctions, and close loopholes in the law that allow oligarchs to use shell companies to move through the U.S. financial system. Andrew Adams, who heads the KleptoCapture task force, designed to enforce the economic restrictions within the U.S. imposed on Russia and its billionaires, told The Associated Press that the group is prioritizing its efforts to identify those who help Russians evade sanctions and violate export controls. “These illicit procurement networks will continue to take up an ever-increasing amount of our bandwidth,” said Adams, who also serves as acting deputy assistant attorney general. So far, more than $58 billion worth of sanctioned Russians’ assets have been blocked or frozen worldwide, according to a report last week from the Treasury Department. That includes two luxury yachts each worth $300 million in San Diego and Fiji, and six New York and Florida properties worth $75 million owned by sanctioned oligarch Viktor Vekselberg. Also Read: US government moves to stop potential banking crisis The U.S. has begun attempts to punish the associates and wealth managers of oligarchs — in Vekselberg's case, a federal court in New York indicted Vladimir Voronchenko after he helped maintain Vekselberg’s properties. He was charged in February with conspiring to violate and evade U.S. sanctions. The case was coordinated through the KleptoCapture group. “I think it can be quite effective to be sanctioning facilitators,” Adams said, calling them “professional sanctions evasion brokers.” A February study led by Dartmouth University researchers showed that targeting a few key wealth managers would cause far greater damage to Russia than sanctioning oligarchs individually. Other attempts to inflict pain on the Russian economy will come from the efforts to liquidate yachts and other property owned by Russian oligarchs and the Kremlin, turning them into cash to benefit Ukraine. Ukrainian President Volodymyr Zelenskyy has long called for Russian assets to be transferred to Ukraine, and former Biden administration official Daleep Singh told the Senate Banking Committee on Feb. 28 that forfeiting Russia's billions in assets held by the U.S. is “something we ought to pursue.” Singh suggested the U.S. should “use the reserves that we have immobilized at the New York Fed, transfer them to Ukraine and allow them to put them up as collateral to raise money.” He ran the White House's Russia sanctions program when he was national security adviser for international economics. Adams said the KleptoCapture task force is pursuing efforts to sell Russians' yachts and other property, despite the legal difficulties of turning property whose owners' access has been blocked into forfeited assets that the government can take and sell for the benefit of Ukraine. He stressed that the U.S. will operate under the rule of law. “Part of what that means is that we will not take assets that are not fully, totally forfeited through the judicial procedures and begin confiscating them without a legal basis,” Adams said. He added that the task force has had “success in working with Congress and working with folks around the executive branch in obtaining authorization to transfer certain forfeited funds to the State Department.” The Treasury Department said on Thursday that the government is “paving the way” for $5.4 million in seized funds to be sent as foreign assistance to Ukraine. Additionally, strengthening laws that serve as loopholes for sanctions evaders will also be a priority across federal departments, officials say. The Financial Crimes Enforcement Network, under Treasury, is expected to roll out rules to address the use of the U.S. real estate market to launder money, including a requirement on disclosing the true ownership of real estate. Steven Tian, director of research at the Yale Chief Executive Leadership Institute, who tracks companies' disengagement from Russia, said the new real estate rule is long overdue. “I would point out that it’s not just unique to Russian oligarchs. As you know, the real estate market makes use of shell companies in the United States, period," Tian said. Erica Hanichak, the government affairs director at the FACT Coalition, a nonprofit that promotes corporate transparency, urged the administration to put the rule forward by late March, when the U.S. co-hosts the second Summit for Democracy with the governments of Costa Rica, Netherlands, South Korea and Zambia. “We’re viewing this as an opportunity for the United States to demonstrate leadership not only in addressing corrupt practices abroad, but looking to our own backyard and addressing the loopholes in our system that facilitate corruption internationally," she said.
