precisely. However China is covering all options and worst case scenarios as well:

The Chinese army has reportedly deployed 150,000 troops to the North Korean border to prepare for pre-emptive attacks after the United States dropped airstrikes on Syria.
President Donald Trump's missile strike on Syria on Friday was widely interpreted as a warning to North Korea.
And now China, left shocked by the air strikes, has deployed medical and backup units from the People's Liberation Army forces to the Yalu River, The troops have been dispatched to handle North Korean refugees and 'unforeseen circumstances', such as the prospect of preemptive attacks on North Korea, the news agency said. It opposes Pyongyang's pursuit of nuclear weapons and ballistic missiles and has signed up to tough United Nations sanctions slapped on North Korea. But it has long been wary of pushing too hard, for fear it could trigger a regime collapse, sending millions of North Koreans surging across the border seeking refuge, while potentially removing a geographic buffer between China and South Korea, a U.S. ally.
