Following Lai's provocative US transit, Beijing had no other option but to hold these joint military exercises around the island as a sharp countermeasure to punish secessionist forces and to safeguard China's sovereignty and territorial integrity. While it's in the PRC's best interest to peacefully reunite Taiwan with the mainland, Lai's provocations and conspiracy with foreign powers can't be tolerated.
While Beijing may see Taiwanese leaders visiting the US as a threat to its claims over the island that it has never been ruled, Chinese warplanes have encroached on Taiwan's air defense zone nearly daily for months. Lai's US trips are just an excuse — China will use every pretext to undermine regional security and continuously oppress its peaceful neighbors.
