US-sanctioned general face of China's growing military
General Li Shangfu, China's new defence minister, is a veteran of the People's Liberation Army's (PLA) modernisation effort - a drive that led the United States to sanction him over the acquisition of weapons from Russia.
Li's tenure starts as Washington pushes to restore military dialogue and communications that soured as Beijing reacted angrily to the August visit to Taiwan by then-US House of Representatives Speaker Nancy Pelosi.
His history as a technocrat - he is an aerospace engineer who worked in China's satellite program - will help him play a key part in meeting the interim targets of President Xi Jinping's goals for the PLA, experts say.
"The operational and technological background of the next Chinese defence minister is especially pertinent given that the PLA aims to become a world-class military by 2049," said James Char, a security scholar at Singapore's S. Rajaratnam School of International Studies.
In 2016, Li was named deputy commander of the PLA's then-new Strategic Support Force - an elite body tasked with accelerating the development of China's space and cyber warfare capabilities.
He was then appointed head of the Equipment Development Department of the Central Military Commission (CMC), China's governing defence body, headed by Xi.
As director, he was named in sanctions imposed by the US State Department in September, 2018 over the purchase of 10 Su-35 combat aircraft in 2017 and equipment related to the S-400 surface-to-air missile system from Russia's main arms exporter, Rosoboronexport.
Asked last week about Li's impending rise, Pentagon spokesman Lieutenant Colonel Marty Meiners said the US military could not comment on media reports about China's leadership changes, but that they had been clear in wanting to maintain communications with the PLA.
"Open lines of communication can help us manage risk, avoid miscalculation and responsibly manage competition," Meiners said.
Oriana Skylar Mastro, a fellow at Stanford University's Freeman Spogli Institute for International Studies, said China was likely to use the dynamic for diplomatic gain - either by presenting the sanctions as immaterial if they are overlooked, or by suggesting it's Washington, not Beijing, that doesn't want to engage.
"Engagement has always been a priority for the US and China sees it as a concession," Mastro said.
Li's term at the Central Military Commission has highlighted his ties to Xi, who has strengthened his grip across the military.
As defence minister, Li is likely to be closely involved with military relations in Asia, attending events such as meetings of Asian defence leaders and the informal Shangri-La Dialogue on security in Singapore.
Also on Sunday, Chen Yixin and Wang Xiaohong remained as ministers of state security and public security, respectively, and Qin Gang and He Rong remained as ministers of foreign affairs and justice, respectively.
