BANGKOK (Reuters) – Thailand is not concerned about the movement of fugitive former Prime Minister Thaksin Shinawatra and his sister after recent visits by the pair to several Asian cities and meetings with members of their party. Thaksin and Yingluck visited China and Japan this month and met at least 30 members of parliament from their Puea Thai party in Hong Kong at the weekend.. The two were spotted in a Singapore hotel on Tuesday, meeting a group of unidentified men, and were in the city state yesterday, party sources said, adding they were having “business meetings”. Political observers say their Asia tour is a sign that their party is gearing up for the election. A spokesman for the junta said it was not focused on the two. “Monitoring those who have an arrest warrant is the job of relevant agencies. We are not concerned about this,” the spokesman, Piyapong Klinpan, said.
