Kiat, a former chief of the Thailand Trade Representative Office, claimed that Yuttapong had made damaging comments at a press conference during the Abhisit Vejjajiva administration.
At Civil Court on Monday, Yuttapong, who was deputy minister for Agriculture and Cooperatives under Yingluck Shinawatra’s administration, said he regretted the remarks and apologised.
Afterwards, the plaintiff decided not to pursue the lawsuit.
