Believed to have a military background,[2] he worked in North Korea's embassy in the Democratic Republic of the Congo in 1968. He was elected as a delegate to the 12th Supreme People's Assembly in 2009.[2]
In October 2013,[2] he was named as ambassador to Peru, presenting his credentials to then president Ollanta Humala on November 8 of the same year.[3] In 2015, he became accredited to Brazil, presenting his credentials on November 3.[4] In September 2017, he was declared a persona non grata by the Peruvian government and given a five-day period to leave the country.[5][6] Prior to leaving the embassy, he held a press conference where he protested the measure.[7][8] Subsequently, the first and third secretaries of the embassy—Pak Myong Chol and Ji Hyok, respectively—were also given the same treatment on December 22,[9] after which they were accused of plotting to attack the families of the diplomatic staff of the U.S. Embassy in Lima, even suggesting their assassination.[10][11]
