Timothy Yang or Yang Chin-tien (; born 1 July 1942) is a Taiwanese diplomat and former Minister of Foreign Affairs and Secretary-General to the President of the Republic of China, serving under President Ma Ying-Jeou.[3]
Yang was born in Ershui, Changhua County[4] and earned his bachelor's degree in diplomacy at the National Chengchi University.
When veteran diplomat Francisco Ou resigned with the Cabinet of Premier Liu Chao-Shiuan in September 2009, President Ma Ying-Jeou named Yang to the post, to serve in the newly formed Cabinet of incoming Premier Wu Den-yih.[5] Prior to becoming Foreign Minister, Yang served as representative to Ireland, Australia,[6] and Indonesia.[7] As Minister of Foreign Affairs he also holds the position of vice-chairman within the Taiwan Foundation for Democracy.
Commenting on the truck attack to the ROC Presidential Office Building in January 2014, Yang said that a team will be established and charged with improving security around the building.[8]
