Thailand’s former premier Thaksin Shinawatra has left Cambodia after spending more than a week stepping up his advisory role and meeting with Thai supporters, an official said Tuesday. Thaksin, who arrived in Phnom Penh on December 13 for a second visit as an economic adviser to the government, departed on Monday morning, said deputy cabinet minister Prak Sokhon.

“He left Cambodia yesterday at around 10am,” he said. Officials would not disclose his destination. During his stay in Cambodia, Thaksin addressed top government officials on how to boost investment, tourism and agriculture.
