Second Trump-Kim Summit Set for 27-28 February in Vietnam

The long speculated on second Trump-Kim summit is set:

U.S. President Donald Trump announced Tuesday that his second summit with North Korean leader Kim Jong-un will be held in Vietnam Feb. 27-28 with the talks to center on dismantling Pyongyang’s nuclear weapons program.
The date and venue had been shrouded in secrecy as the two countries negotiated the next steps following a vague denuclearization deal reached at their first summit in Singapore in June.
“Much work remains to be done, but my relationship with Kim Jong-un is a good one,” Trump said during his State of the Union address.

I wonder what the Chinese government thinks of the summit being in Vietnam considering their past brief military war and current territorial disputes in the South China Sea? This is a growing indication of how much the US-Vietnam relationship continues to positively develop which I would think the Chinese government would not be happy about.
