Thailand is not concerned about the movement of fugitive former Prime Minister Thaksin Shinawatra and his sister, also an ousted former leader, after recent visits by the pair to several Asian cities and meetings with members of their party.

The Shinawatras have dominated Thai politics for nearly two decades and wield significant influence through allies and relatives despite both living in self-exile. They are likely to be a significant factor in a general election the junta has promised for November.

Critics say the military, which took power in a 2014 coup that removed Yingluck Shinawatra's government, wants to end the family's political influence — something that is reflected in a new, military-backed charter, party laws and restrictions on political parties.
