> This is a blunt challenge to a series of UN Security Council resolutions.
And it acts to threaten the peace and safety of the international community, as well as the Korean Peninsula.>> US Pacific command says the weapon was likely a KN-15. A medium ranged missile.

Wednesday's launch comes a day before US President Donald Trump sits for talks with Chinese President Xi Jinping where a discussion over how to curb the North's arms program will top the agenda. That includes on whether Trump will make good on his threat to squeeze trade ties with China, twisting Beijing's arm to reign in an unpredictable Pyongyang.
A senior White House official told Reuters, Trump views the North as a test of US China relations. Beijing says it doesn't have that kind of pull with its unruly neighbor.
