The Taipei Economic and Cultural Office (TECO), also known as the Taipei Representative Office, serves as Taiwan's official representative in various countries. Operating as an alternative to an embassy, its core mission is to promote bilateral trade, investment, cultural, scientific, and technological exchanges.

TECO handles foreign affairs and citizen services, including issuing visas and passports. These offices enjoy significant privileges, such as consular protection and diplomatic immunity, ensuring smooth international cooperation. By using the name "Taipei," these offices facilitate easier relations globally. TECO is an essential hub for fostering understanding and cooperation between Taiwan and host nations.
