SEOUL (Reuters) - North Korea’s new nominal head of state is a long-time loyalist with deep ties to the ruling Kim family and whose fortunes have closely followed the rise of leader Kim Jong Un, analysts said.

Choe Ryong Hae was named President of the Presidium of the Supreme People’s Assembly of North Korea, state media reported on Friday, replacing Kim Yong Nam who had held the position since it was created in 1998.

In that position, Choe will be the constitutional head of state, and is likely to be the public face of North Korea at many official functions.

With Kim Jong Un personally taking an unprecedented role in international engagement, Choe’s role may evolve. But analysts say Choe now holds a position of rare prominence for anyone outside the Kim family, which has ruled North Korea since it was established in 1948.

Born in 1950, Choe began to forge his relationship with Kim Jong Un after being tasked in 2009 to help him prepare to succeed his father, Kim Jong Il.

Choe’s father had ties to Kim Il Sung, Kim Jong Un’s grandfather and the founding leader of North Korea, and Choe himself had a personal relationship with Kim Jong Il for decades.

Choe was one of the most powerful officials in North Korea as head of the Workers’ Party of Korea Organization and Guidance Department (OGD), according to database North Korea Leadership Watch.

He survived years of purges after Kim Jong Un took power, and has weathered a series of ups and downs in his standing.

In late 2015, South Korea’s National Intelligence Service said Choe had been sent to a countryside farm for political reeducation, but in recent years Choe appeared to be gaining more influence since he was promoted in October 2017 to the party’s powerful Central Military Commission.

South Korea’s spy agency said in 2017 it believed he was behind the punishment of General Hwang Pyong So, once one of Kim Jong Un’s most-trusted advisers.

Still, analysts said Choe appears to be more of a smooth “yes man” than a hardened enforcer within the government.

“He is a schmoozer,” said Michael Madden, a North Korea leadership expert at the Stimson Center, a U.S. think tank. “He’s not one of these guys with bloody knuckles, not someone we would associate with being a leg-breaker in the regime. He knows how to do that if he needs to, but he’s more of a schmoozer.”

In December, Choe was one of three North Korean officials sanctioned by the U.S. Treasury Department for “serious human rights abuses and censorship”.

In a statement at the time, the department said as head of the OGD, Choe oversaw censorship and control of North Koreans.

A former South Korean diplomat who met Choe said that even during meetings where he was not the most senior official, Choe seemed “confident, or even arrogant”, often doing most of the talking.

“I had the impression that he had the trust of Kim Jong Un, which would’ve come from his father’s relationship with the Kim family,” the diplomat said, speaking on condition of anonymity due to the sensitivity of the issue.
