Chea Sim, head of the ruling Cambodian People's Party and Second Prime Minister Hun Sen's party archrival, will visit Tokyo as early as September under the Foreign Ministry's Opinion Leaders Invitation Program, ministry sources said Wednesday.

The sources said that Chea Sim, who also serves as head of the Southeast Asian country's parliament, recently accepted the Japanese invitation. Although the invitation said Japan would welcome Chea Sim as soon as possible, specific dates for the trip have yet to be set.
