In the letter on Friday, Kim praised the efforts of workers in various fields and industries in his country, according to CGTN.

Earlier on Monday, North Korea's official media published a new letter from the country's leader to the South African president amid rumors of his health.

Rumors about the North Korean leader's illness surfaced after a report was published by CNN claiming that Kim Jong Un had not attended several official events and is probably ill.
