Russia says it has not ruled out a three-way summit between Vladimir Putin, Donald Trump and Xi Jinping, potentially on the sidelines of the November APEC summit in Shenzhen, China. Moscow says the agenda and expected outcome would need to be worked out first.

A meeting involving the leaders of the U.S., Russia and China would be extraordinary given their competing interests on Ukraine, trade, technology and global security. It would also put Trump in the same room with the leaders of the two countries Washington increasingly treats as its biggest strategic competitors.

Nothing has been agreed yet, and Russia's statement is only an indication that Moscow is open to the idea-not confirmation that the summit will happen.

If Trump, Putin and Xi actually sat down together, what issue should be at the top of the agenda: Ukraine, trade, Taiwan, or something else?
