China again vowed to “fight to the end" Wednesday in an escalating trade war with the US as it announced it would raise tariffs on American goods to 84% from Thursday.

Beijing also added an array of countermeasures after US President Donald Trump raised the total tariff on imports from China to 104%, AP reports.

Beijing said it was launching an additional suit against the US at the World Trade Organization and placed further restrictions on American companies' trade with Chinese companies.

“If the US insists on further escalating its economic and trade restrictions, China has the firm will and abundant means to take necessary countermeasures and fight to the end,” the Ministry of Commerce wrote in a statement introducing its white paper on trade with the US.

The government declined to say whether it would negotiate with the White House, as many other countries have started doing.

On Friday, China announced a 34% tariff on all goods imported from the US, export controls on rare earths minerals, and a slew of other measures in response to Trump's “Liberation Day” tariffs. Trump then added an additional 50% tariff on goods from China, saying negotiations with them were terminated.

Wednesday's newest measures include adding 11 American companies to a so-called “unreliable entities” list that would bar Chinese companies from selling them dual-use goods. Among the companies are American Photonics, and SYNEXXUS, both of whom work with the American military.

So far, China has not appeared interested in bargaining. “If the US truly wants to resolve issues through dialogue and negotiation, it should adopt an attitude of equality, respect and mutual benefit,” said Ministry of Foreign Affairs spokesman Lin Jian Wednesday.
