David Lee Ta-wei (; born 15 October 1949) is a Taiwanese politician and diplomat who is the chairman of Straits Exchange Foundation May to August 2020 and from January 2023 to May 2024. He formerly served as the Minister of Foreign Affairs from May 2016 to February 2018,[1] Secretary-General of the National Security Council of Taiwan from February 2018 to May 2020, and the Secretary-General to the President since 3 August 2020 to 31 January 2023.[2]
Speaking in August 2016, Lee said that Taiwan will continue to pursue meaningful participation in the United Nations (UN) agencies. However, he will not promote Taiwan to apply for UN membership.[3]
During his ministerial term, Lee visited Palau to attend the inauguration of President Tommy Remengesau in January 2017, Haiti to attend the inauguration of President Jovenel Moïse in February 2017 and Solomon Islands in June 2017.[4] [5] [6]
On 11 March 2022, a special force soldier wrote a letter to President Tsai Ing-wen reporting the insufficient basic logistic supply which has compelled the combatants to purchase from outsider suppliers at their own expense for two years, then being disqualified as non-standard upon inspection, in contrast of the reserve trainees receiving new sets; and appealed to abolish the mandatory diary writing for examination.[7] [8] The classified "2022006470" paper was taken photo illegally from the presidential palace and leaked to the media with his identity exposed on 18 March; hence Minister of National Defense Chiu Kuo-cheng reacted: "I will not let him get away with it", "Fix the crying baby!"; but later clarified while being questioned by the parliament members in the Legislative Yuan, that he just disgusts the coward behavior behind his back, and the critique unfair to the preparatory staff.[9] [10] The incident raised the broad society concern on the standard operating procedure practice on the data security breach in the presidential office.[11]
