China’s Expanding Maritime Military Presence Alarms Taiwan and Japan

Taiwan and Japan expressed growing concern on Friday over China’s expanding military activity across East Asian waters, following a Reuters report revealing Beijing’s largest maritime deployment to date. According to intelligence reviewed by Reuters, China positioned more than 100 naval and coast guard vessels this week across key waterways, marking an unprecedented show of force in the region.

Taiwan presidential spokesperson Karen Kuo noted that the deployment extended far beyond the Taiwan Strait, reaching from the Yellow Sea to areas near the disputed Senkaku Islands, and further into the South China Sea and western Pacific. She warned that such extensive operations threaten Indo-Pacific stability and urged Beijing to act with restraint as a “major power.” Taiwan President Lai Ching-te has directed security forces to maintain heightened vigilance and provide timely updates, while coordinating closely with international partners to safeguard regional peace.

In Tokyo, Japan’s Defence Minister Shinjiro Koizumi acknowledged awareness of the reports and emphasized that Japan is monitoring China’s military maneuvers “with great attention.” He reiterated that China has been steadily increasing its activities around Japan, prompting the government to intensify surveillance and intelligence gathering.

China has yet to comment on the reported deployments, but foreign ministry spokesperson Lin Jian stated that Chinese naval and coast guard operations comply with domestic and international law, urging other nations not to “overreact or engage in baseless speculation.”

The heightened activity comes during China’s traditionally busy military exercise season and surpasses the scale of its December operations last year, which led Taiwan to raise its alert level. Tensions are already elevated as China faces diplomatic friction with Japan after Prime Minister Sanae Takaichi indicated that a Chinese attack on Taiwan could trigger Japanese military involvement. Beijing is also displeased with Taiwan’s recent announcement of an additional $40 billion in defense spending as it continues to reject China’s territorial claims.
