HONG KONG - The US unclear powered aircraft carrier USS George Washington pulled in Hong Kong waters on Wednesday to get replenishment upon her second portal call to the city.

Captain David Lausman, commanding officer of the USS George Washington, told the press briefing that the Chinese navy acted professionally when they encountered.

"Chinese navy had great improvement in the past two or three decades. We are looking forward to working with them in the future," he added.

Commissioned in 1992, the 332-meter, 97,000-ton USS George Washington carries a crew of more than 5,000. The sailors will stay in Hong Kong for about 5 days and participate in some volunteer work.
