Would Beijing back away from its strategic partnership with Moscow if the war in Ukraine goes nuclear? DW asks Chinese foreign policy expert, Andy Mok.

Just days before Russia invaded Ukraine, President Vladimir Putin meet his Chinese counterpart Xi Jinping in Beijing. The two leaders announced a friendship without limits. Now in the third month of war, how is the partnership holding up? With no end in sight,are some Chinese limits possible? Would Beijing back Moscow's use of nuclear weapons in the conflict as Russian officials have threatened? Questions for Chinese foreign policy expert Andy Mok, a senior research fellow at Beijing's Center for China and Globalization.

He blamed the US for instigating the war and defended Moscow: "Russia is part of Europe…its concerns must be addressed."

What implications will Russia’s war have for China’s goal of unification with Taiwan?

With Taiwan, clearly the government’s position has been: peaceful reunification is the goal…but if other courses of action became inescapable, then that is also on the table as well," Mok told DW’s Tim Sebastian.
