One of the elementary rules of foreign policy is when you are in a hole, stop digging. But judging by their recent behavior, Beijing’s foreign policy mandarins and national security establishment are clearly in violation of this rule. Despite the diplomat heat China has received for its tough stance on territorial disputes in recent months, the Chinese Foreign Ministry apparently seemed to believe that it could strengthen Chinese claims symbolically by issuing a new passport containing a map that claims the disputed maritime areas in the South China Sea and the contested territories along the Sino-Indian border. The reaction was predictable. Southeast Asian countries, particularly Vietnam and the Philippines, protested loudly. India retaliated by promising to stamp visas containing its own map on Chinese passports.
