The Taiwan Affairs Office of China's State Council slammed Taiwan's Democratic Progressive Party authorities on Wednesday for forbidding any local officials from any people-to-people exchanges with the mainland. The DPP authorities confirmed earlier on Wednesday that they will investigate Rao Ching-ling, head of Taiwan's Taitung County, for possible prosecution after she praised cross-Strait business deals signed last week via a video clip. Rao was blocked by the DPP authorities from traveling to the mainland last week to attend the Straits Forum, the largest cross-Strait people-to-people exchange event.
