President Donald Trump’s deadline for Russia to end its war in Ukraine or suffer severe economic punishment expires Friday, but it’s unclear how he plans to proceed amid new efforts toward a summit with Vladimir Putin and delicate trade negotiations with China.

No location has been set for a potential meeting between the two leaders, but officials are eying the United Arab Emirates, Hungary, Switzerland and Rome.

A bilateral meeting between President Donald Trump and Russian President Vladimir Putin could happen as soon as next week, according to a White House official.
