The world’s largest maritime law enforcement agency played an unprecedented role in Chinese military drills around Taiwan, simulating a blockade of the island.

China has made it clear that it won't hesitate to use military force if Taiwan pushes for independence, signaling an escalation in tensions.

Beijing’s massive military drills around Taiwan on Monday revealed significantly improved coordination between its navy and coastguard, according to observers, who say this could be key to mainland China’s blockade strategy for the island.
