FILE - In this Tuesday, July 4, 2017, file photo, people watch a local TV news showing what was said to be the launch of a Hwasong-14 intercontinental ballistic missile, ICBM, aired by North Korea's KRT, at Seoul Train Station in Seoul, South Korea. Despite U.S. President Donald Trump's hopes for China's help in dealing with North Korea and his recent tough talk on the matter, the two sides seem to be growing further apart as their approaches and concerns diverge. China shows no sign of caving in to U.S. pressure to tighten the screws on North Korea, while the North's recent missile tests have done little to rattle Beijing. China's bottom line continues to hold: no to any measures that might topple Kim Jong Un's hard-line communist regime. The part of letters at bottom read: "North Korea, Kim Jong Un ICBM Launch."
