Siriwat is vice-president of the National Olympic Committee of Thailand and the head of the country's hockey association.

He is also vice-president of the Asian Hockey Federation (AHF), which congratulated him on his appointment by the OCA.

"Dato Seri Chaiyapak Siriwat will work closely with the OCA in the successful execution of the 6th Asian Indoor and Martial Art Games in Bangkok and Chonburi in 2021," the AHF said.

"Dato Seri Chaiyapak Siriwat, based out of Thailand, has had an illustrious career in sports management and the Government of Thailand. 

"He served as the Minister to the Prime Minister’s Office, the Deputy Minister of Transport and Communication and the Deputy Minister of Interior. 

"In the sports world he has held many important positions over his career in tennis, football and hockey sports bodies.
