Given the following context:  On the last day of British rule in Hong Kong late 1997, Detective Inspector Lee of the Hong Kong Police Force leads a raid at a shipping bar wharf, hoping to arrest the mysterious crime lord Juntao. He finds only Sang, Juntao's right-hand man, who manages to escape. However, Lee successfully recovers numerous Chinese cultural treasures stolen by Juntao, which he presents as a farewell victory to his departing superiors: Chinese Consul Solon Han and British Commander Thomas Griffin. Shortly after Han arrives in the United States to take up his new diplomatic post in Los Angeles, his daughter, Soo Yung, is kidnapped by Sang while on her way to her first day of school. The FBI informs Consul Han about the incident. Han calls in Lee to assist in the case. The FBI, afraid that the injury or death of Lee would result in negative attention internationally, decides to pawn him off on the LAPD just to keep him out of their way. The selfish, stubborn, and maverick Detective James Carter is tricked into doing this but Carter makes a plan to solve the case himself when he finds out that he has been given a boring task as punishment for botching a sting operation. Carter meets Lee at Los Angeles International Airport and proceeds to take him on a sightseeing tour of LA, simultaneously keeping Lee away from the embassy and contacting several of his underworld informants about the kidnapping. Lee finally escapes and makes his way to the Chinese Consulate, where a nervous Han and a group of FBI agents are awaiting news about his daughter. While arguing with Agent-in-charge Warren Russ, Carter accidentally involves himself in a phone conversation with Sang, where he arranges a ransom drop of $50 million in a couple of hours.  answer the following question:  What is the last name of the person who goes to Los Angeles for a diplomatic post?
The answer to this question is:
Han
