Two of Chinese Navy battleships, have arrived in Hong Kong for a five day visit.

The ships are in town for the ceremony of the 15th anniversary of Hong Kong's return to China in 1997. They were returning from a month-long escort mission fighting pirates in Somali waters and the Gulf of Aden.

This is the second time the vessels have made a port call to Hong Kong since Chinese naval ships began escorting missions five years ago. The vessels will be opened to Hong Kong residents for tours through Thursday.
