 Russia asked China for military and economic assistance in the Ukraine conflict, following the invasion

The United States has warned that China will face severe "repercussions" if it helps Russia in its invasion of Ukraine, according to US media.

And media reports said that Russia had requested military and economic aid from China.

But the Chinese embassy in Washington made it clear that it did not know anything about this request, which was covered by the reports.

The Financial Times said Moscow wanted Beijing to provide it with military supplies for use in Ukraine.

The newspaper quoted US officials, who did not reveal their identity, as saying that Russia had requested Chinese equipment since the beginning of the invasion. Officials declined to say what kind of equipment Russia was seeking.

There are indications that China may be preparing to help, the report added.

The New York Times also quoted US officials as saying that Moscow had also requested economic aid to mitigate the impact of the sanctions.

In an interview with CNN, US National Security Adviser Jake Sullivan said that during direct communication with Beijing, it was clear the consequences of "any large-scale attempts to circumvent sanctions or help Russia overcome them."

"We will not allow these (attempts) to go ahead and allow Russia to have a lifeline to overcome these economic sanctions by any country and anywhere in the world," he added.

China has so far sought to portray itself as neutral in the Russian-Ukrainian conflict and has not denounced the invasion.

On Monday, the US National Security Adviser is expected to hold talks with senior Chinese foreign policy official Yang Jiechi in Rome.

In response to a question about media reports that Russia has requested military aid from China, a spokesperson for the Chinese Embassy in Washington said that Beijing is focused on "not getting the war in Ukraine out of control."

"The situation in Ukraine is indeed alarming," said embassy spokesman Liu Bingguo.

"The top priority now is to prevent the tense situation from escalating or even spiraling out of control," he added.

When asked about press reports about Russia's request for weapons from China, the spokesman said he had "never heard of that."

"No flight"

As Russian attacks in Ukraine continued, Ukrainian President Volodymyr Zelensky urged NATO again to impose a no-fly zone over his country. Otherwise, he warned, it will only be a matter of time before Russia targets NATO members

The president spoke after a Russian missile attack on a Ukrainian base near the Polish border, which left thirty-five people dead.

Zelensky added that he had spoken to the President of the European Council, Charles Michel and that Ukraine's hopes of joining the European Union had "become a reality".

Zelensky described the ongoing negotiations between the Ukrainian and Russian delegations as complex and difficult, but necessary for peace and security.

He said Ukrainian officials aimed to secure direct peace talks between the leaders of the two countries - a meeting he said he was sure people were waiting for.

More talks are scheduled for Monday.

On Sunday, Ukrainian and Russian negotiators made cautiously optimistic assessments of the talks. Ukraine said the Russians had stopped issuing ultimatums, and the Russians also spoke of making significant progress.

On the field front, the Ukrainian military said that as Russian forces continued their offensive, they had moved strategic reserves towards Ukraine's borders.

The latest bulletin from the Ukrainian General Staff says that Russia is also preparing to regroup forces, and resume offensive operations on the cities of Kharkiv, Sumy, and the eastern suburbs of the capital, Kyiv.

She added that Sunday witnessed strategic air attacks on the towns of Uman, Starichi, and Ivano-Frankivsk. She said that the launching of missiles from Belarusian territory continues.

"second wave"

Regarding the refugee crisis, officials in Poland have warned that they are struggling to absorb refugees, with the country bearing the brunt of Europe's largest refugee movement since World War II.

Of the 1.7 million Ukrainians who have crossed into Poland since the invasion began, about 1 million remain.

In small border towns, in particular, authorities say that shelters are running out of capacity and resources are running out.

The BBC's correspondent at the border said officials had warned the new arrivals could soon be sleeping on the streets. He said they fear there could be a second wave of refugees if the fighting in Ukraine moves west after Russia attacks a Ukrainian military base near the Polish border.
