China has launched a strategic missile from a nuclear-powered submarine into the South Pacific Ocean, causing diplomatic tension with the United States and several regional countries.

中國從一艘核動力潛艇向南太平洋發射了一枚戰略飛彈，導致與美國及幾個區域國家的外交緊張。

This operation is a major step in the People's Liberation Army's (PLA) goal to create a 'nuclear triad,' which allows them to launch nuclear weapons from land, air, and sea. While the Chinese government emphasized that the event was a routine exercise to check the system's reliability, experts believe the use of the JL-3 missile—which can travel 10,000 kilometers—shows China's intent to project power across the Pacific. Furthermore, reports from the Centre for Strategic and International Studies indicate that China's nuclear arsenal has tripled over six years and may exceed 1,000 missiles by 2030.

此次行動是中國人民解放軍（PLA）旨在建立「核三位一體」的重要步驟，使其能從陸地、空中和海洋發射核武器。雖然中國政府強調此次事件是檢查系統可靠性的例行演習，但專家認為使用射程達 10,000 公里的 JL-3 飛彈，顯示出中國意圖將權力投射至整個太平洋。此外，戰略與國際研究中心的報告指出，中國的核武庫在六年內增加了三倍，到 2030 年可能會超過 1,000 枚飛彈。

Regional countries have reacted with worry, mainly because the missile entered the South Pacific Nuclear Free Zone. Australia and the Solomon Islands expressed concern over the lack of transparency and the provocative nature of the test. Consequently, Australia has increased its security agreements with Vanuatu, Fiji, and Papua New Guinea to counter China's influence. Additionally, the history of nuclear testing in the Pacific by Western nations has made local people more sensitive to environmental and health risks.

區域國家對此表示擔憂，主因是該飛彈進入了南太平洋核免區。澳洲與所羅門群島對缺乏透明度及測試的挑釁性質表示關注。因此，澳洲加強了與萬努阿圖、斐濟和巴布亞紐幾內亞的安全協議，以對抗中國的影響力。此外，西方國家過去在太平洋進行核試驗的歷史，使得當地民眾對環境和健康風險更加敏感。

Diplomatically, the event has caused a confrontation between Beijing and Washington. The United States asserted that China's secretive nuclear buildup is a global security risk and called for formal arms control talks. In contrast, the Chinese Foreign Ministry dismissed these claims as 'double standards,' arguing that the U.S. has a larger arsenal and conducts similar launches. China maintains that its strategy is strictly defensive and follows international law.

在外交上，此次事件引起了北京與華盛頓的對峙。美國聲稱中國秘密擴充核武是全球安全風險，並要求進行正式的軍控談判。相反，中國外交部將這些指控斥為「雙重標準」，認為美國擁有更大的武庫且也進行過類似的發射。中國堅持其戰略純屬防禦性並符合國際法。

The current situation is marked by increasing regional tension as China adds advanced sea-based nuclear capabilities to its military strategy.

目前的局勢特徵是，隨著中國將先進的海基核能力加入軍事戰略，區域緊張局勢日益升溫。
