Russia's energy minister, Alexander Novak, entered the OPEC headquarters without answering journalist's questions as officials prepared to take up the cartel's proposal to cut output by 1.5 million barrels a day, of 1.5% of world production.
OPEC countries like Saudi Arabia and Iran say they need non-member allies to take 500,000 barrels of that cut on themselves.
Analysts say OPEC may struggle to keep oil prices from falling further.
Right now, the international crude benchmark trades a little over $50 per barrel, down from $69 in January before the outbreak. The spread of the coronavirus has sharply reduced air travel and thus the demand for fuel, while industry in China, the world's second largest economy, has been severely disrupted through shutdowns and travel restrictions.
Some economists think the global economy may shrink in the first quarter for the first time since the financial crisis, sapping demand for energy.
Oil production in the U.S., which is not part of OPEC and unlike Russia does not cooperate in its output decisions, has ramped up in recent years, flooding the market and keeping prices down.
