Shortly after North Korea conducted another ballistic missile test, President Trump took to Twitter late Monday to ask if Kim Jong-un had anything "better to do with his life."

"North Korea has just launched another missile. Does this guy have anything better to do with his life? Hard to believe that South Korea and Japan will put up with this much longer. Perhaps China will put a heavy move on North Korea and end this nonsense once and for all!" Trump wrote.

North Korea has conducted almost a dozen missile tests in 2017.

Trump has been pushing China, sometimes through tweets, to take a tougher stance against North Korea as the latter works to develop a nuclear missile capable of reaching the U.S.

Trump was briefed on the latest missile test Monday night, according to the White House.
