The main opposition Democratic Party of Korea (DPK) on Thursday urged the government and the ruling party to come up with a supplementary budget worth 35 trillion won ($24.2 billion) to support the nation's economy.

During a press conference at the National Assembly, DPK lawmakers unveiled the budget plan, which allocates 24 trillion won for improving people's livelihood and 11 trillion won for economic growth.

Among the livelihood budget is the issuance of currency vouchers designed to help small merchants and the self-employed, which the DPK has been seeking in line with a signature policy of its leader Lee Jae-myung.

The 13 trillion-won program offers 250,000 won cash coupons to the entire 50 million population across the country, with an additional 100,000 won for low-income households and other vulnerable groups.

The DPK also called for a 2.8 trillion-won budget to support small business owners affected by the economic downturn caused by the aftermath of President Yoon Suk Yeol's short-lived martial law declaration on Dec. 3, as well as the Dec. 29 Jeju Air crash at Muan International Airport. (Yonhap)
