China hit back on Monday after U.S. President Donald Trump tweeted he was "very disappointed" in China following North Korea's latest missile test, saying the problem did not arise in China and that all sides need to work for a solution.
China has become increasingly frustrated with American and Japanese criticism that it should do more to rein in Pyongyang. China is North Korea's closest ally, but Beijing, too, is angry with its continued nuclear and missile tests.
North Korea said on Saturday it had conducted another successful test of an intercontinental ballistic missile that proved its ability to strike the U.S. mainland, drawing a sharp warning from Trump and a rebuke from China.
