Sun Weidong

Sun Weidong was born at a town in Xuzhou Prefecture in September 1966. From 1989 to 1996 he taught at China Foreign Affairs University.^[3]

He joined the Foreign Service in 1996 and has served primarily in Southeast Asia. From 2005 to 2008 he was counsellor of Chinese Embassy in India.^[4] After returning to China he was appointed deputy director of Asia Department of the Ministry of Foreign Affairs. He served as the Chinese Ambassador to Pakistan from 2013 through 2017. Then he was director of the Department of Policy Planning of the Ministry of Foreign Affairs.

In 2019, the 13th Standing Committee of the National People's Congress appointed him Chinese Ambassador to India, replacing Luo Zhaohui.^[5] On 28 August 2019, he along with ambassadors of three other countries presented their credentials to President of India Ram Nath Kovind.^[6]

Sun's tenure as ambassador witnessed the worsening of relations between China and India following the border skirmishes between Indian and Chinese troops in June 2020 near Galwan Valley, resulting in the deaths of 20 Indian and four Chinese soldiers. In the aftermath of the border clashes, the Government of India banned 59 Chinese mobile apps and placed restrictions on Chinese economic investments in India.^[7][8] In an interview with the Press Trust of India on 25 June 2020, Sun stated that "mutual respect and support is a sure way and meets the long-term interests of both countries; suspicion and friction is a wrong path and goes against the fundamental aspiration of the two peoples" and then proceeded to blame the Indian side for instigating the border clash stating the onus to resolve border tensions was not on China.^[9][10]

During the second wave of COVID-19 pandemic in India in 2021 when China provided medical equipment to India, Sun stated that "China was not absent or sat back apathetically" which was seen as a dig towards the United States who was a key partner of India but was slow in reaching out during the second wave of the pandemic.^[11] Sun served this position till October 2022.^[12] During his farewell ceremony, he stated that "if the western theory of geopolitics is applied to China-India relationship, then major neighbouring countries like us will inevitably view each other as threats and rivals" which was seen as a cautionary remark against the West. While at the same time, he stated that "when China and India maintain stability and development, it means that two-fifths of the world’s population has access to development opportunities. The healthy development of China-India relations will bring more stability and certainty to the world."^[13]

On 15 November 2022, he was appointed vice-minister of Foreign Affairs.^[3] In May 2023, he summoned then Japanese ambassador to China Hideo Tarumi to protest after the heads of state at 49th G7 summit in Hiroshima issued statement regarding rising tensions in South China Sea and Taiwan Strait as well as the human rights situations in China, including in Tibet and Xinjiang.^[14] That same month in a meeting in Beijing, he warned Cagayan governor Manuel Mamba on hosting foreign troops such as the United States in the Philippines. He also reiterated that China preferred a bilateral approach to handle maritime disputes.^[15] In January 2024, he visited North Korea where he met with Minister of Foreign Affairs of North Korea Choe Son-hui. During his meeting with Choe, both China and North Korea pledged to strengthen strategic communications "at all levels" and reaffirmed "unswerving stance" on deepening ties.^[16] In June 2024, he met with First Deputy Foreign Minister of Ukraine Andrii Sybiha and during the meeting, Sybiha urged China to send delegation to the June 2024 Ukraine peace summit in Switzerland from June 15 to June 16. In a transcript of the meeting released by the Ministry of Foreign Affairs of China stated the two sides "exchanged views on the Ukrainian crisis and international and regional issues of common concern" but made no mention of Sybiha's request for China to attend the summit.^[17] In November 2025, amidst a diplomatic crisis with Japan, Sun summoned Japanese ambassador to China Kenji Kanasugi to protest remarks made by Japanese Prime Minister Sanae Takaichi about Japanese involvement in a war over Taiwan. Sun stated that "The Taiwan issue is the core of China’s core interests and is a red line that must not be crossed" and "if anyone attempts to interfere with the great cause of China’s reunification, China will inevitably strike back."^[18] On 14 April 2026, he was dismissed as Vice Minister of Foreign Affairs.^[19]
