China's naval activity has intensified in recent weeks, with two warships encircling Japan's southwestern islands, prompting concerns from the Japanese Defense Ministry about incursions into its exclusive economic zone. The Chinese Type 052D destroyers, Nanjing and Lishui, were observed moving through key waterways, indicative of Beijing's expanding military presence in the region. Concurrently, the Philippine Navy reported the presence of three Chinese corvettes during joint drills with the U.S., Canada, and Australia, though officials downplayed the threat. Meanwhile, Chinese military construction continues unabated in the South China Sea, where several artificial islands have been militarized, raising alarms about a 'creeping invasion' of the Philippines' territorial waters. The ongoing tensions have led to calls for more joint maritime exercises among allied nations to bolster regional security. These developments reflect a broader strategy by China to assert its maritime claims amid rising geopolitical tensions in East Asia.
