An expert in Asian security says he’s hoping North Korea “acts up” during President Trump’s two-day meeting with Chinese President Xi Jinping this week, because it could force the two countries to cooperate.

Cronin noted that North Korea fired missiles when Japanese Prime Minister Shinzo Abe was meeting with Trump in the U.S.
