Something big is afoot here.
A little history. The Japanese took British Hong Kong at the beginning of hostilities WW2. The US Navy liberated the Pacific including Hong Kong from the Japanese.
Ever since then, the US Navy has been warmly received in Hong Kong...even AFTER the British turned it over to the Chicoms. But now this.
This may be the first evidence of a sea change (no pun intended) in Chicom-Hong Kong, and Chicom-US relations.
Give the Brits some credit. They and other commonwealth forces liberated Hong Kong peacefully on August 15, 1945.
Your post adds alot of intrigue to this story.
Allow me to update your history log.
>>China banned U.S. ships entering Hong Kong waters in 1999 when NATO planes bombed the Chinese embassy in Belgrade during the Kosovo crisis and refused port calls for several months after a U.S. spy plane collided with a Chinese fighter jet in April, 2001.<<
