Thailand’s famous National Artist Chalermchai Kositpipat made the headlines this week after he sponsored a project that turned a graffiti covered wall into street art that’s attracting visitors to Chiang Rai.

Nakhon Ratchasima’s Culture Office has invited more than 30 graffiti artists to create works on the theme ”Korat: the art city” after the government named Chiang Rai, Krabi, and Nakhon Ratchasima or Korat as it is colloquially known, as pilot cities for arts. The city has also been selected to host the 2nd Thailand Biennale, a biannual international contemporary art exhibition.
