Joint marine training bearing the terrorism on the ocean and the measure against a pirate in the Strait of Malacca which is the important place of the seaborne traffic of Southeast Asia in mind was expected to carry out by the framework of the ASEAN Regional Forum (ARF) which consists of 24 nation and mechanisms, such as the Association of Southeast Asian Nations (ASEAN) and inside of Japan and the U.S., in 2006. The last adjustment is advanced aiming at agreement at the ARF defense working-level talks and this Cabinet meeting which are held in Vientiane at the end of this month. Training is likely to serve as an opportunity to which Japan and the U.S. etc. make participation expand involving the security in this strait. Training received having adopted the declaration turned to cooperation strengthening under "a threat, such as piracy," at the Cabinet meeting which ARF held in Phnom Penh in 2003, and Singapore proposed it as the embodiment measure. As for training, according to the proposal document which our paper received, an ARF member's navy, Coast Guard, etc. participate for the purpose of "improvement in marine peace capability." Desk training turned to communalization of an operations procedure besides exercises on the ocean, such as management training to the attack by the small boat and surveillance of a navigation ship, on the high seas or in the territorial waters of a member nation is carried out. Singapore is raising introducing itself to the host nation of the 1st training. If the security of the Strait of Malacca is revolved, it is the position in which Indonesia and Malaysia are opposite to participation of a third power absolutely as "invading independence and sovereignty (coastal country)" (Prime Minister Abdullah of Malaysia) to asserting "correspondence by the multi-country-framework" in which small Singapore of navy power included the U.S. etc. among coastal countries. If especially the U.S. is traveled, the Fargo U.S. Pacific Command commander expresses the intention to dispatch rice navy Special Forces for the measure against terrorism in this strait in 2004, and there are circumstances where Indonesia and Malaysia opposed violently. However, the actual condition is that both countries cannot take terrorism and measures against a pirate sufficient by superannuation of a navy warship, or shortage of the number of boats, and it is offering improvement support in capability etc. to "It is unanimous" at indirect participation of an extra territorial country. U.S.'s probability which had backed up this training design, carried out [ probability ] "conceding greatly" (diplomatic source) from the conventional attitude of aiming at direct participation, and was changed to the cooperation posture with Indonesia etc. is large. Training carries out "reliance brew" to a dialog or exchange from beginning to end at a title, and attracts attention also as first concrete measure by ARF which was being asked about the significance of existence.
