The government naturally has a firm grasp of how to orient itself for talks with mainland China, too. You can imagine the tremendous pressure the negotiators are under from both within and without Taiwan. The lead negotiators have to be able to bear up under this pressure and remain focused on their objectives.
至於中國大陸，政府當然會掌握對其談判的方向，可以想見過程中來自國內外的壓力都很巨大，主談者最重要的是抗壓性要夠，要能守住自己的目標。
