China replaces foreign minister Qin after mysterious absence

China named veteran diplomat Wang Yi its new foreign minister on Tuesday, removing former rising star Qin Gang after a mysterious one-month absence from duties barely half a year into the job.

Qin, 57, a former aide to President Xi Jinping and envoy to the United States, took over the ministry in December but has not been seen in public since June 25 when he met visiting diplomats in Beijing.

The ministry has said he was off work for health reasons but gave no details, sparking speculation and drawing attention to the secrecy often surrounding China's Communist leadership and decision making.

Qin's successor Wang, 69, was also his predecessor, holding the post from 2013-2022 as ties frayed with rival superpower the United States to a point Beijing described as an all-time low.

He has filled in for Qin during his absence and represented China at a national security advisers' meeting of BRICS countries in Johannesburg, South Africa this week.

State media did not report why Qin was removed from office and China's foreign ministry did not respond to a request for comment.

Xi signed a presidential order to make the decision effective, state news agency Xinhua reported.

It is not the first time there has been an unexplained absence of officials in China.

Industry minister Xiao Yaqing disappeared from public view for nearly a month last year before it was revealed he was being investigated for corruption.

Qin was one of China's youngest foreign ministers, enjoying a meteoric ascent that analysts partly attributed to his closeness to Xi.

He was twice foreign ministry spokesman, between 2006-2014, and chief protocol officer from 2014-2018, overseeing many of Xi's contacts with foreign leaders.

He headed to Washington as ambassador in July 2021, after a period of unusual public vitriol between US and Chinese officials.

Wang was promoted to the politburo of the Chinese Communist Party, one of China's top leadership bodies.

He retakes the foreign ministry post as China seeks to re-engage with the world after years of COVID-induced isolation, as a mooted economic recovery fails to gain hold and the country spars with the United States over issues from Ukraine, Russia and Taiwan to trade and technology disputes.

"The choice of Wang Yi is rational," said Yun Sun, director of the China Programme at the Stimson Center in Washington.

"To convey a sense of stability and credibility, China needs to select someone who is senior, authoritative and impeccable," she said.

Hours after news of his appointment broke, Pakistan's Foreign Minister Bilawal Bhutto Zardari tweeted his congratulations, saying Wang was "an astute and seasoned diplomat".

As for Qin's political future, that remains unclear, say analysts, pointing out that there has not yet been any clarity over whether he will still hold his role as state councillor, a member of China's cabinet.
