South Korean President Moon Jae-in will unveil an array of TV talent and K-pop celebrities at events, including a state dinner, in China on Thursday as he attempts to smooth out a year of difficult diplomacy with a star-laden charm offensive.

South Korean celebrities, including some of those accompanying Moon, had been shut out of Chinese television and concert halls as relations cooled between the East Asian neighbors as they faced the threat posed by North Korea's missile and nuclear programs.

The thorniest issue was South Korea's deployment of a controversial U.S. anti-missile system.
