The event will host 300 guests under the theme of "Sustainable Thai Gastronomy" at the Thai Royal Navy Convention Hall, Bhakavat Tanskul, director-general of the Foreign Affairs Ministry's Protocol Department said on Monday.
Chumpol Jangprai, executive chef at R-Haan, a two Michelin star restaurant, will lead the cooking team, Mr Bhakavat said.
