The Taipei Economic and Cultural Representative Office in the Kingdom of Saudi Arabia; (Chinese: 駐沙烏地阿拉伯王國台北經濟文化代表處; pinyin: Zhù Shā Wū Dì Ālābó Wángguó Táiběi Jīngjì Wénhuà Dàibiǎo Chù; Arabic: مكتب الممثل الإقتصادي والثقافي لتايبيه في المملكة العربية السعودية, romanized: Maktab Almumaththil Al'Iiqtasadi Walththaqafi Litayibih fi Almamlakat Alearabiat Alssaeudia) represents the interests of the Republic of China (Taiwan) in Saudi Arabia in the absence of formal diplomatic relations, functioning as a de facto embassy.

[2][3][4][5] In addition, it has responsibility for Taiwan's relations with Afghanistan, Djibouti, Ethiopia, Pakistan, Qatar and Sudan.

[8] Until 1990, Taiwan had diplomatic relations with Saudi Arabia, and was represented by the Embassy of the Republic of China in Riyadh.

[10] However, in that year, Saudi Arabia recognised the People's Republic of China.

[12] Both offices were set up in 1991, following the signing of a secret memorandum six months after the severing of diplomatic relations.
