"There was a nexus" between the U.S. spy agency and Kim, the person said.
Kim, the half brother of North Korean leader Kim Jong Un, was killed in Kuala Lumpur International Airport in Malaysia in February 2017, when two women smeared his face with the nerve agent VX. U.S. and South Korean officials have blamed the attack on North Korea, which it denies.
Many details of Kim’s relationship with the CIA remain unclear. Several former U.S. officials said the half brother, who had lived outside of North Korea for many years and had no known power base in Pyongyang, was unlikely to be able to provide details of the secretive country’s inner workings.
They also said Kim ‐ who resided mainly in the Chinese enclave of Macau ‐ was almost certainly in contact with security services of other countries, particularly China’s. The CIA declined to comment. Chinese officials didn’t respond to a request for comment. The fact that the CIA held meetings with the North Korean leader’s exiled half brother illustrates the lengths U.S. intelligence will go to gather information about the hermetic country.
