Manila summons Chinese ambassador over maritime tensions. Defense Secretary Gilberto Teodoro challenged China to submit the claims to international arbitration.
The Philippines said China's coast guard blocked one of its supply ships on Saturday and damaged it with powerful water cannon blasts, wounding three soldiers. It is the same place where ships from both sides have collided in recent months, creating similar standoffs. China claims almost the entire South China Sea, rejecting all claims by other neighboring countries and an international ruling that its claims have no legal basis.
