China-South Korea ties: empty ambassador chair highlights complications in relationship

China has been without an ambassador in South Korea for more than three months, the longest vacancy since the two countries established diplomatic ties.

Some diplomatic observers said the choice of a new ambassador might reflect the need to consider a growing number of geopolitical challenges, but others said the delay may not have any special significance and suggested Beijing may have other diplomatic priorities.

Beijing has made no announcement on its next ambassador since Xing Haiming left the position on July 10, having served in the role since January 2020. The embassy is currently run by Fang Kun, the charge d'affaires.

Recently vacancies in China's ambassadorial roles to the European Union and the United States have also been left unfilled for an extended period.

In May last year, former foreign vice-minister Xie Feng was appointed as ambassador to Washington, a role that had been vacant for almost five months, the longest period since US-China relations normalised in 1979.

Last month, China's former ambassador to Israel Cai Run became the country's new envoy to the European Union, filling a vacancy that had been open since March.

According to Chung Jae-hung, director of the Centre for Chinese Studies at the Sejong Institute in Seoul, complex geopolitical tensions might require China to consider more factors when selecting its candidate for South Korea than had previously been the case.

"With the strengthening of the US-South Korea-Japan relations and the growing hostility between North and South Korea, South Korea is likely to increase its pressure on China regarding these matters in the future. This raises the question of how China should approach relations between North and South Korea," Chung said.

"Economically, China and South Korea's priorities also diverge: South Korea seeks cooperation in China's market, especially in services and finance, while China looks to chips and advanced industries where cooperation is limited."

The position may remain vacant for a few more months, partly to allow Beijing to observe the state of US-South Korea relations after the US election, Chung said.

China and South Korea maintain robust trade ties but these have been tested in recent years by Seoul's closer security and political relations with Washington under the Yoon Suk-yeol administration.
