An unnamed senator revealed that Ukraine is lobbying US Congress members to oppose a peace plan proposed by China, Punchbowl News reported on Monday.

Over the weekend, Ukrainian officials distributed materials to congressional representatives opposing the plan, ahead of the annual UN General Assembly in New York, where global leaders, including Volodymyr Zelensky, are set to convene.

Chinese officials are also expected to present their proposal, calling on Western countries to halt their support for Ukrainian strikes into Russian territory.

Meanwhile, Congress has been urging the Biden administration to remove restrictions preventing Ukraine from launching deeper strikes into Russia.

Ukraine reportedly criticized China's plan as self-serving, accusing Beijing of attempting to bolster its relationship with Moscow.

In February 2023, China released a 12-point document titled "China's Position on the Political Settlement of the Ukraine Crisis," which outlined measures for a peace process in Ukraine.

It called for respect for the sovereignty of all countries, the cessation of hostilities, and the resumption of peace talks between Moscow and Kiev.

Russian President Vladimir Putin said that some of the provisions of the plan could be a basis for a peace settlement "if the West and Kiev are ready for it."

Beijing has consistently reiterated its support for a diplomatic resolution to the conflict in Ukraine and expressed opposition to actions by countries that align with one side.

Earlier this month, Chinese Vice Foreign Minister Chen Xiaodong said that China will continue engaging with all parties to facilitate peace talks on Ukraine.
