The hijacking of a China Airlines cargo plane on May 3 , 1986 shattered the " Three Noes " policy . The pilot Wang Shi-chuen subdued the two other members of the flight crew and commandeered the plane to Guangzhou , forcing the ROC government to publicly send unofficial envoys to negotiate in Hong Kong with PRC officials over the return of the plane and the flight crew . The pilot , credited by the PRC for reestablishing contact between mainland China and Taiwan , received a hero ’s welcome in mainland China and became a senior PRC aviation official as well as serving as a so-called " Taiwanese delegate " to PRC government institutions
