South Korea is to get tough with seafarers who flout its Covid-19 testing procedures with heavy fines and potential imprisonment.

With immediate effect any violation of the country’s polymerase chain reaction (PCR) test submission requirement could result in a penalty of up to KRW 10m ($8.4m) or up to a year in jail.

Seafarers also face potential punishment if they submit forged or false PCR certifation, according to shipping agency GAC.
