China has proposed holding a Trump / Putin summit

Chinese officials in recent weeks have floated a proposal to the Trump team through intermediaries to hold a summit between the two leaders and to facilitate peacekeeping efforts after an eventual truce, according to people in Beijing and Washington familiar with the matter.

That's according to the Wall Street Journal report (gated):

• China Tries to Play the Role of Peacemaker in Ukraine
  • U.S. and Europe would view Beijing’s proposal skeptically given its close ties to Moscow

More:

• The Chinese offer, notably, envisions a U.S.-Russian summit without the involvement of Ukrainian President Volodymyr Zelensky, according to the people in Beijing and Washington. The prospect of the U.S. negotiating the future of Ukraine and of European security with Russia and China is contrary to the West’s longstanding pledge to include Ukraine in any talks to decide its future. The White House declined to confirm whether it had received China’s offer, but still rejected it. “Not viable at all,” a White House official said.
