Taiwan's Ministry of National Defence (MND) reported the presence of six Chinese naval vessels operating around its territorial waters as of 6 a.m. local time on Sunday, June 28, 2026. The MND announced this detection via a post on X, stating that the Republic of China (ROC) Armed Forces have monitored the situation and responded accordingly. No flight path illustration was provided, as no People's Liberation Army (PLA) aircraft were detected during this timeframe.
Previous Day's Detection
On Saturday, June 27, 2026, the MND had detected a sortie of Chinese military aircraft and seven naval vessels operating around Taiwan's territorial waters. In a separate post on X, the MND confirmed that ROC Armed Forces were monitoring the situation. The consistent presence of Chinese military assets highlights an ongoing pattern of increased activity near Taiwan.
Taiwan's Submarine Sea Trials
In a related development, Focus Taiwan reported earlier in June that Taiwan's first domestically built submarine departed from the Port of Kaohsiung for its latest round of sea trials, which included dive tests. According to the Military News Agency, this trial marked the submarine's 15th sea trial overall and its ninth submerged navigation test. The submarine program is part of Taiwan's efforts to bolster its defensive capabilities amid rising Chinese military pressure.
Context of China's Claims
China's claim over Taiwan is rooted in historical, political, and legal arguments, with Beijing asserting that Taiwan is an inseparable part of China. This stance is embedded in national policy and upheld by domestic laws and international statements. Taiwan, however, maintains a distinct identity, functioning independently with its own government, military, and economy. The status of Taiwan remains a significant point of international debate, testing principles of sovereignty, self-determination, and non-interference in international law, according to the United Service Institution of India.
China's claim to Taiwan originates from the Qing Dynasty's annexation of the island in 1683 after defeating Ming loyalist Koxinga. The current increase in Chinese military incursions underscores the ongoing tensions in the region.
