President Yoon Suk Yeol called Tuesday for dealing with the liquidity crisis at e-commerce platforms TMON and WeMakePrice "thoroughly according to the law," his office said.

Yoon gave the instruction during a Cabinet meeting at the presidential office, saying it is the government's duty to "strongly separate and isolate" rule violations in the market, according to presidential spokesperson Jeong Hye-jeon.

"Take action thoroughly according to the law," he was quoted as saying. "The financial authorities must continue to monitor the situation."

TMON and WeMakePrice have failed to pay vendors their earnings amid a liquidity crisis at their Singapore-based owner Qoo10, prompting thousands of customers to swarm the two companies' headquarters and demand refunds.

During the opening of the Cabinet meeting, which was broadcast live, Yoon touted the selection of a South Korean consortium as the preferred bidder for the construction of two nuclear reactors in the Czech Republic.

The project, valued at an estimated 24 trillion won ($17.3 billion), is Korea's first overseas nuclear power plant project since 2009.

"A strong bridgehead has been established to enable our entry into the 1,000 trillion-won global nuclear power market," he said. "I thank deeply all the businesspeople and nuclear sector workers who ran together as Team Korea, and all the people who gave their support."

Yoon again stated plans to draw up a special bill supporting the nuclear power industry, saying it took "much effort" in the process of being selected as the preferred bidder to overcome damaged trust, which he attributed to the nuclear phase-out policy of the previous administration.

"I will personally visit the Czech Republic at an early date to discuss the success of the nuclear power project and ways for in-depth bilateral cooperation," he said.

Yoon also noted the success of a different "Team Korea" competing at the Paris Olympics.

Naming the athletes who have won medals so far, he praised them for further elevating Korea's status in the world.

Yoon additionally reaffirmed plans to protect and support retail investors by scrapping the financial investment income tax, which is set to be introduced next year, and adopting tax incentives that encourage dividend payments. (Yonhap)
