The government is seeking to revise laws to increase financial transparency of labor unions to make it harder for improper spending to take place, the labor minister said Monday.

The proposal comes after a series of remarks by President Yoon Suk-yeol who emphasized bolstering oversight of unions. He also described corruption in labor unions as one of the top three types of corruption that need to be eliminated.

"There is growing mistrust among the people in labor union's financial management, whether finances are managed transparently and disclosed in accordance," Labor Minister Lee Jeong-sik told a press briefing.

Prior to the revision, the government first plans to induce unions with more than 1,000 members and federations to inspect their own financial accounting documents.
