Philippine President Rodrigo Duterte visited Chinese warships docked in his hometown on Monday, Xinhua News Agency reported.

Duterte boarded the guided missile destroyer Changchun, which arrived with two other vessels in Davao city on Mindanao island on Sunday for a three-day goodwill visit.

Duterte said he is open to the idea of conducting joint military exercises with China. "I agree (to the idea). They can have joint exercises here in Mindanao, maybe in the Sulu Sea," Duterte told reporters after visiting the warship at the Davao city wharf.
