"The Chinese Government requests for port visits to Hong Kong by USS Green Bay and USS Lake Erie, which were scheduled to arrive in the next few weeks," Cmdr. Nate Christensen, the deputy spokesman for the US Navy's Pacific Fleet, told CNN in a statement on Tuesday.
The amphibious ship dock USS Green Bay was scheduled to visit Hong Kong on August 17 and the missile-cruiser USS Lake Erie
Not the first time
"The US Navy has a long track record of successful port visits to Hong Kong and we expect them to continue The Chinese Government for further information about this request, "Christensen said.
The US has denied having any role.
President Donald Trump tweeted Tuesday that "our intelligence has communicated with the Chinese Government is moving to the border with Hong Kong. Everyone should be calm and safe."
