LONG-TIME allies the United States and the Philippines on Thursday blasted North Korea's "provocative" rocket launch as a threat to regional security and pledged to strengthen their military ties.

In a statement following bilateral talks attended by top diplomats and security officials, the two countries vowed to boost cooperation in the wake of Pyongyang's move.

They agreed to bolster joint efforts relating to maritime security, disaster response, law enforcement and cyber-security, and non-proliferation (of nuclear weapons), the statement said.

"The two sides also strongly condemned . . .  [the launch] utilizing ballistic missile technology and emphasized that this highly provocative act is in direct violation of relevant UN Security Council resolutions," the statement said.

"Given this current threat to regional security, both sides will strengthen and increase their close alliance coordination," it said.

The meeting was attended by US Assistant Secretary of State Kurt Campbell, Assistant Secretary of Defense Mark Lippert and their Filipino counterparts Erlinda Basilio and Pio Batino.

The US considers the Philippines a major non-NATO ally in the Asia Pacific region, where Washington had earlier announced a strategic shift of its forces.

Filipino officials previously said that they hoped the Philippines could play a key role in that pivot, with a former US naval base north of Manila already increasingly accommodating American carriers and submarines.

The meeting also came at a time when the Philippines, along with other Southeast Asian countries, is embroiled in an increasingly tense territorial dispute with China involving territories in the West Philippine Sea (South China Sea).

Washington had earlier warned China against its perceived aggressiveness in staking out its claims.
