A Chinese invasion of Taiwan would not succeed should the U.S. and Japan back Taipei but it would come at a high cost for all parties involved, the influential Center for Strategic and International Studies (CSIS) said. However, China would also suffer “high losses” that might destabilize Chinese Communist Party rule. Beijing considers Taiwan a Chinese province and “China’s leaders have become increasingly strident” about unifying the island with the mainland, therefore a military invasion is “not out of the question,” the report said.
