Liu said “utmost efforts should be made to support Russia and Ukraine in carrying forward negotiations despite the difficult situation to produce a peaceful outcome”.
Sullivan told CNN on Sunday that Washington believed China was aware that Russia was planning some action in Ukraine before the invasion took place, although Beijing may not have understood the full extent of what was planned.
Now, he said, Washington was watching closely to see to what extent Beijing provided economic or material support to Russia, and would impose consequences if that occurred.
“We are communicating directly, privately to Beijing, that there will absolutely be consequences for large-scale sanctions evasion efforts or support to Russia to backfill them,” Sullivan said.
“We will not allow that to go forward and allow there to be a lifeline to Russia from these economic sanctions from any country, anywhere in the world.”
A senior Biden administration official said the war in Ukraine and its impact on regional and global security would be a “significant topic” during Sullivan’s meeting with Yang, given China’s moves to align “itself with Russia to advance their own vision of the world order. “
The meeting, which had been in planning for some time, is part of a broader effort by Washington and Beijing to maintain open channels of communication and manage competition between the world’s two largest economies, the official said.
No specific results were expected, the source added, speaking on condition of anonymity.
Washington and its allies have imposed sweeping, unprecedented sanctions against Russia and banned its energy imports, while providing billions of dollars of military and humanitarian assistance to Ukraine.
The United States on Saturday said it would rush up to $US200 million worth of additional weapons to Ukrainian forces as they try to defend against Russian shelling in the largest war in Europe since World War II.
Individually and together they have appealed to China, Gulf nations and others that have failed to condemn the Russian invasion to join in isolating Russia from the global economy.
Beijing, a key trading partner of Russia, has refused to call Russia’s actions an invasion, although Chinese President Xi Jinping last week did call for “maximum restraint” in Ukraine after a virtual meeting with German Chancellor Olaf Scholz and French President Emmanuel Macron.
Xi also expressed concern about the impact of sanctions on global finance, energy supplies, transportation and supply chains, amid growing signs that Western sanctions are limiting China’s ability to buy Russian oil.
Wang Huiyao, head of a Beijing think tank and adviser to the Chinese government, warned of “an escalatory spiral” in a column published in the New York Times on Sunday, and said China was “uniquely positioned to act as a neutral mediator between a Western-supported Ukraine and Russia” to end the war.
“Unpalatable as some in the West may find the idea, it is time to offer the Russian leader an off-ramp with China’s help,” Wang wrote.
