President Lee Jae Myung on Tuesday touted the tax office's ongoing search for hidden overseas assets, calling tax justice a "very important value."

Lee wrote the message on his X account, a day after the National Tax Service (NTS) announced it had retrieved 33.9 billion won (US$23 million) in evaded taxes since July last year from foreigners and nationals living abroad. 

"Tax justice is a very important value," Lee said, referring to an X post by NTS Commissioner Lim Kwang-hyun, in which he pledged to track down hidden overseas assets and ensure they are taxed. 

"I thank Commissioner Lim Kwang-hyun for his hard work after he gave up his parliamentary seat and took up the post as NTS chief."
