According to international relations expert Pang Zhongying, Sun's links with the Liaison Department and her expertise in inter-party diplomacy could play a key role in strengthening relations between China and Singapore's ruling People’s Action Party. On 31 May, she presented her credentials to President of Singapore Halimah Yacob. According to The Washington Post, Sun's first engagement after being appointed as ambassador to Singapore was a meeting with a group of Singaporean Chinese-language online outlets.

On 16 August 2022, following Speaker of the United States House of Representatives Nancy Pelosi's visit to Taiwan on 2 August 2022, Sun issued a statement stating that the visit "not only violates the U.S. own official one China principle, infringes on China's sovereignty, but also threatens the whole region's stability" and will not "allow this unprovoked challenge to our sovereignty pass without appropriate responses."

In September 2022, she oversaw the signing of the extension agreement of pandas Kai Kai and Jia Jia stay at Mandai Wildlife Reserve till 2027.

She became the first female to serve as deputy minister in the Liaison Department.
