Japan, the United States, and several allied nations have conducted the Balikatan military exercises in the Philippines, featuring the first deployment of Japanese combat troops and live-fire missile tests.

日本、美國及數個盟國在菲律賓舉行了「肩並肩」軍事演習，其特點在於首次部署日本戰鬥部隊並進行導彈實彈測試。

The Balikatan exercises, involving approximately 17,000 personnel from the United States, Philippines, Japan, Australia, Canada, France, and New Zealand, concluded on May 8. A primary operational highlight was the deployment of two Japanese Type-88 surface-to-ship missiles, which successfully neutralized a decommissioned Philippine navy corvette approximately 75 kilometers off the coast of the South China Sea. These activities were augmented by the participation of Japan's Amphibious Rapid Deployment Brigade in counter-landing maneuvers and the inaugural deployment of ShinMaywa US-2 amphibious aircraft for medical and rescue operations. Furthermore, the United States and Philippines utilized the Navy-Marine Expeditionary Ship Interdiction System (NMESIS) in Batanes, situated approximately 100 miles south of Taiwan.

「肩並肩」演習於5月8日結束，涉及美國、菲律賓、日本、澳洲、加拿大、法國及紐西蘭約17,000名人員。其中一項主要作戰亮點是部署了兩枚日本88型艦對艦導彈，成功擊毀了一艘位於南海沿岸約75公里處的菲律賓海軍退役巡邏艦。此外，日本水陸機動旅參與了反登陸演習，且首次部署ShinMaywa US-2水陸兩用機執行醫療與救援任務。此外，美國與菲律賓在位於台灣南方約100英里的巴坦島使用了海軍陸戰隊遠征艦艇攔截系統 (NMESIS)。

These maneuvers coincide with a systemic shift in Japanese security architecture under Prime Minister Sanae Takaichi. The administration has transitioned toward a more assertive defense posture, characterized by the acquisition of counterstrike capabilities, increased military expenditures, and the relaxation of restrictions on the export of lethal military hardware. This strategic pivot is evidenced by the recent procurement of 11 warships by the Australian navy from Mitsubishi Heavy Industries. The rapprochement between Tokyo and its regional allies is viewed by some analysts as a response to shared concerns regarding island defense.

這些演習正值高市早苗首相領導下，日本安全架構發生系統性轉變。該政府已轉向更為強勢的國防姿態，其特徵為獲取反擊能力、增加軍事開支，以及放寬致命軍事裝備的出口限制。澳洲海軍近期向三菱重工業採購11艘軍艦，便證明了這一戰略轉向。部分分析師認為，東京與其區域盟友之間的關係改善，是對島嶼防禦共同憂慮的回應。

Beijing has responded to these developments with formal condemnation. The Chinese Foreign Ministry characterized the missile tests as an acceleration of Japanese remilitarization and an evasion of historical accountability. This diplomatic friction was exacerbated by Prime Minister Takaichi's previous assertions regarding potential Japanese military intervention should China attempt to annex Taiwan. Consequently, China has implemented trade restrictions and advised its citizens against travel to Japan. Simultaneously, regional middle powers continue to employ hedging strategies, attempting to balance security assurances from Washington with the necessity of maintaining economic stability and trade relations with Beijing.

北京對此發展採取正式譴責。中國外交部將導彈測試定性為加速日本重新軍事化，且在逃避歷史責任。由於高市首相先前聲明，若中國嘗試併吞台灣，日本可能進行軍事干預，使得外交摩擦進一步加劇。因此，中國實施了貿易限制，並建議公民避免前往日本旅遊。同時，區域中等強國繼續採取對沖策略，試圖在華盛頓的安全保證與維持與北京的經濟穩定及貿易關係之間取得平衡。

The exercises have demonstrated increased interoperability among Western-aligned forces, while simultaneously intensifying diplomatic tensions between Japan and China.

此次演習展示了親西方陣營軍隊之間互操作性的提升，但同時也加劇了日本與中國之間的外交緊張關係。
