Before coming to Taiwan, the group met with Wang Daohan in Hangzhou for a meeting on bilateral security issues, discussing the current state of military exchanges between the mainland and the US, and sensitive matters such as the "Theater Missile Defense" (TMD) system and the cross-strait situation.
來台前，已與汪道涵在杭州進行「美『中』安全問題研討會」，討論雙方的軍事交流現況，其中也包括敏感的「戰區飛彈防禦體系 TMD」與台海議題。
