The list contains personal information and malicious comments about emergency doctors who chose to treat patients rather than join their colleagues who have been absent from work since February in protest of the government's increased admission quota for medical schools. reported the Yonhap news agency.

"The blacklist is a mockery and insult to medical staff caring for patients and a cowardly act that effectively strips individuals of their free will," Han said during a central disaster response meeting.

"It is a very serious criminal act. The government will not tolerate it," he added.

According to the Ministry of Health, more than 30 people have been referred to the prosecutor's office for their participation in the blacklisting of doctors working in emergencies.

"Law enforcement authorities should investigate the case severely and quickly," Han said. "I also call on the medical community to actively participate in efforts to correct the misconduct of some doctors."

Han reiterated the call for the medical community to join a consultative body with the government, ruling and opposition parties and doctors' groups to discuss medical school admission quotas and other medical reform measures.

"If the medical community puts forward a scientific and reasonable plan on medical school fees and policy plans, the government is willing to discuss it with an open attitude," Han said.

Most trainee doctors have left their workplaces since February in protest against the government's plan to sharply increase the admission quota for medical schools from next year.

The prolonged strike has raised concerns about possible disruptions to medical services during the upcoming five-day Chuseok holiday, which begins Saturday.

To address concerns, the government designated September 11-25 as a special period and created an emergency task force to manage the situation at emergency medical centers across the country.
