TAIPEI: Taiwan said on thursday that it was closely watching the Chinese military, which it said posed a rising threat to the region, after a flurry of warplanes passed near the island to join drills with China's Shandong aircraft carrier in the Pacific. The Chinese military exercises coincide with a Nato summit in Washington, where a draft communique says China has become a decisive enabler of Russia's war effort in Ukraine, and Beijing continues to pose systemic challenges to Europe and to security.
