In response to transformations in the international environment, TBA began actively engaged in international interchanges after the 1970s to assist the government in promoting citizen diplomacy by organizing various exchange events and activities such as calling members to attend The Law Association For Asia And The Pacific (LAWASIA). The 15th board of directors adopted the resolution for appointed TBA delegates to visit bar associations of countries which do not have official ties with Taiwan to enhance citizen diplomacy and make known the rule of law and legal system in Taiwan. During the 1980s, TBA held interchanges with the Seoul Bar Association, Gwangiu Bar Association, New York City Bar Association, Daini Tokyo Bar Association and the Johannesburg Bar and signed an interchange agreement with the Seoul Bar Association.

After the 1990s, with the globalization in all aspects, professional organizations need to operate with international perspective in order to establish cross-border cooperation to access and integrate information. Since the signing of the interchange agreement with the Okinawa Bar Association in 1994, TBA has actively built friendly relationships with the bar associations in various Asian cities. As of 2010, TBA has entered into alliances with the Queensland Bar Association, Seoul Bar Association, and Daini Tokyo Bar Association. In addition, TBA has joined several international law-related NGOs; for instance, TBA joined the International Commission of Jurists (ICJ) in July 2001 and became actively involved in the international affairs concerning human rights protection.

Furthermore, the interactions among both sides of the Straits, Hong Kong and Macau became more frequent than ever since 2008. In addition to actively maintaining friendly exchanges with practicing attorneys visiting from the other regions and participating in various city forums, TBA has signed interchange agreements with the Shenzhen Bar Association, Beijing Lawyers Association and Hong Kong Law Society. The objective is to guide the TBA members into the cross-strait as well as the international legal services market and broaden the members' perspective.
