Navy Ship in Japan

TOKYO -- In a sign of increasing cooperation, a Russian navy destroyer called at a Japanese military port Thursday for the first time this century.

The 6,700-ton Admiral Panteleyev entered port at Japan's fleet headquarters in Yokosuka, southwest of Tokyo. It is on a five-day visit for friendly exchanges and a joint exercise with a Japanese destroyer.

The Japanese and Russian navies have been deepening their ties in recent years. Last month, the two countries agreed to set up a hot line to warn each other of potential threats at sea. The two countries have yet to sign a peace treaty officially ending their World War II hostilities.
