File- In this file image taken on Nov. 3, 2008, China's top negotiator with Taiwan, Chen Yunlin, waves to media as he arrives at the Taoyuan International Airport, in Taoyuan, Taiwan. President Ma Ying-jeou's signature effort to boost ties with Beijing faces a key test next week when Taiwan's pro-independence opposition takes to the streets to protest the visit of the senior Chinese envoy. Buoyed by a strong showing in local elections earlier this month, the Democratic Progressive Party says it will muster 100,000 supporters Sunday in the central city of Taichung ahead of Monday's arrival of Chen Yunlin, China's top Taiwan negotiator.
