BEIJING • When China rejuvenates its top leadership team towards the end of the year, sources close to senior leaders say President Xi Jinping could reveal his grip on power with a possible leapfrog promotion for Guizhou Communist Party boss Chen Min'er.
Mr Chen, a trusted confidant of Mr Xi, has already ridden on the coat-tails of his former boss since they worked together in Zhejiang, where Mr Xi was provincial party leader, and three sources with leadership ties think he could jump straight into the seven-member Politburo Standing Committee (PSC) during the 19th party congress of the Chinese Communist Party (CCP).
In national politics, Mr Chen is currently only a member of the 205-member Central Committee, and an elevation to the PSC would involve a two-step promotion, missing out the 25-member Politburo.
"Chen Min'er is a dark horse," said a Chinese official who has worked with him. "He has a good relationship with Xi and is very competent. He gets things done."
"At the very least, Chen Min'er will become a member of the Politburo," a source with ties to the leadership told Reuters.
Mr Chen spent the first three decades of his career steadily rising through the party ranks in his native Zhejiang, where his career began to dovetail with Mr Xi's from 2002, when the latter secured his first top provincial-level appointment.
An avid reader and Chinese calligraphy buff, Mr Chen worked closely with Mr Xi for more than four years as Zhejiang's propaganda chief, running Mr Xi's column in the provincial newspaper and cultivating his growing profile. In 2012, he left Zhejiang to become Guizhou deputy party secretary. Less than a year later, and within roughly a month of Mr Xi becoming president, he was promoted to governor, before being promoted again to his current role as Guizhou party boss in 2015.
"This is a person you certainly should pay a lot of attention to ... Xi Jinping really paved the way for his promotion," said Chinese elite politics expert Cheng Li at the Brookings Institution. "He's known not only for his close ties with Xi but he's also a popular leader both in Zhejiang and Guizhou, so that puts him on a very fast track for promotion."
China's State Council Information Office, which doubles as the spokesman's office for the Cabinet and the party, and the Guizhou government did not respond to requests for comment.
For decades, Guizhou was one of China's most backward provinces, but in recent years the central government has poured in billions of yuan. Guizhou's economy almost doubled between 2012 and last year, when it posted the second-highest growth among China's 31 provinces and municipalities, and Mr Chen has not been reticent in drawing attention to either his achievements or connections. "Chen actually says he is close to Xi," said one China-based diplomat who has met him.
Other Xi allies seen as possible contenders include Mr Li Zhanshu, who heads the party's general office, and Mr Zhao Leji, head of the Organisation Department, which oversees personnel decisions.
Another Xi lieutenant, top corruption buster Wang Qishan, who is already on the PSC, could be kept on despite having passed the unofficial retirement age of 68.
The PSC is ostensibly chosen by a vote in the Central Committee, but results are typically preordained by an opaque process involving horse- trading between the president, outgoing PSC members and party elders who remain influential.
If Mr Xi does prove strong enough to appoint Mr Chen to the PSC, it could be at the expense of candidates from rival factions, such as Guangdong party chief Hu Chunhua, from the Communist Youth League (CYL) group close to former president Hu Jintao, or Chongqing party boss Sun Zhengcai.
Chongqing, however, was criticised by the party's anti-corruption watchdog this month for not doing enough to root out the influence of its former party chief Bo Xilai, jailed for life for a graft scandal in 2013.
Two-time Politburo member Wang Yang, a vice-premier from the CYL faction, is also a contender.
