Spanish Prime Minister Pedro Sanchez has encouraged Chinese President Xi Jinping to consider Ukraine's proposal to end the Russian invasion of its country.

Sanchez said at a Beijing press conference on Friday that he notified Xi that Spain supported Ukrainian President Volodymyr Zelenskyy's proposals to end the war. The recent demands included a request for Russia to restore Ukrainian territory that was taken during and after the annexation of Crimea in 2014.

"I believe it's a plan that lays the foundations for a durable peace in Ukraine and is perfectly aligned with the United Nations charter and its principles, which have been violated by (Russian President Vladimir) Putin with his invasion," Sanchez said.

"I transmitted our concern over the illegal invasion of Ukraine," the prime minister added, saying that he encouraged Xi to talk with Zelenskyy one-on-one.

Sanchez's comments come after Beijing released its own take on an ideal political solution to the war in Ukraine. However, China's position paper did not acknowledge that Russia was the aggressor.

Sanchez did commend that China's paper respected territorial integrity and "its complete and categorical rejection of not only the use but even the threat to use nuclear weapons."

Xi recently expressed a desire to end the "Cold War mentality" in geopolitics and "extreme" sanctions, but did not call out Russia.
