Sangrat did not mention when Rajapaksa intended to travel to Thailand.
Anger has been building in Sri Lanka for months as the country’s foreign exchange reserves fell to record lows, with dollars running out to pay for essential imports including food, medicine and fuel.
The former leader’s hasty exit last month was a historic moment for the nation of 22 million people, which the Rajapaksas had ruled with an iron fist for much of the past two decades before losing the confidence of citizens in theirs.
Rajapaksa is not the first member of the family to be president. His brother Mahinda Rajapaksa was elected to the top post in 2005 and achieved near-legendary status in 2009 when he declared victory in the 26-year civil war against the rebel Liberation Tigers of Tamil Eelam.
Gotabaya Rajapaksa served as defense secretary at the time and the brothers were accused by human rights groups of committing war crimes — charges the family denies.
Recently, many Sri Lankans have accused the Rajapaksas of mismanaging the country’s economy.
After storming the presidential palace, thousands of excited Sri Lankans swam in Gotabaya Rajapaksa’s swimming pool, sang in his dining room and danced around the rich grounds of what was one of the country’s most protected buildings.
Wickremesinghe appears to have distanced himself from the Rajapaksas, telling CNN last month that the previous government was “covering up facts” about its damaging financial crisis.
