South Korea is suspending direct flights from the UK by another week until January 28th.
And for people arriving from Brazil, it'll be strengthening its quarantine measures from January 25th, but details have not been released yet.
This was announced by the government on Tuesday, as concerns mount over the new COVID-19 variants.
South Korea has reported 18 cases of the new virus strains so far,15 from the British variant, two of the South African variant and one of the Brazilian variant.
Starting Monday, South Korea has been testing everyone who enters the country within one day of their arrival, rather than within three days as was done before.
South Korea on Tuesday added 386 new COVID-19 cases, keeping the daily tally under 400 for the second straight day.
Of those, 351 were locally transmitted and 35 were from overseas.
A total of about 38-hundred cases were reported last week, down 29 percent from the week before.
The health authorities credit the decline to the country's tougher social distancing measures.
"There has been an overall decrease in the number of patients, and we believe it is because of decreasing large-scale cluster infections from places like religious facilities and nursing hospitals."
However, the government warned that infections could soar again at any time, and urged people to socially distance and take other precautions.
As of Tuesday, the total number of the COVID-19 cases in the country stands at 73,115, with the death toll of one,283.
