"This is an exercise to build friendship and trust."

The dispute has long been seen as a potential military flashpoint in the region.
Tensions have increased in recent years as China has sought to cement its claims with the building of artificial islands in the sea and installing military aircraft and missile systems on them.
The Philippines, under the previous presidency of Benigno Aquino, had rallied ASEAN to take a united stand against Chinese actions in the sea and won a ruling from an international tribunal that China's claims were unlawful.
Ng said China wanted to conduct the joint exercise next year and Singapore would help arrange it
"We will work out the details, the (logistics) and find a suitable area that ASEAN and China navies can exercise together," Ng said.
Singapore is the ASEAN-China coordinator and will next year hold the regional grouping's rotating chairmanship.
US Defence Secretary James Mattis also attended the two- day event, during which North Korea's nuclear ambitions were one of the top agenda items.
