Prime Minister Prayut Chan-o-cha will on Thursday visit flood victims in Ubon Ratchathani, one of four provinces hit hardest by the inundation, according to a Government House itinerary.
The premier will pay a trip to Warin Chamrap district, where the worst flooding in the province has submerged two-storey houses.
Aside from meeting victims and handing out relief supplies, Gen Prayut will also lead an activity to collect rubbish from the Moon River.
Meanwhile actor Bin Bunluerit, who is leading a charity-relief campaign for Ubon Ratchathani, said public donations reached 332 million baht on Wednesday.
Bin also dismissed rumours he would merge his campaign with that of the government, which critics say has been slow to respond to the crisis.
The rumours may have emerged after he appeared on a televised government fundraiser for flood victims on Tuesday night, he said.
"I took part in the special TV programme because, as an actor, I can help the government out with this good cause -- not because I intend to merge [the donation projects]," he told media.
He rejected speculation that he had a problem with the government or anyone in government.
He also reassured the public that every effort would be made to ensure transparency in managing and spending the money donated to his fund.
Of the more than 332 million baht donated so far, 22 million baht has already been withdrawn, 10 million on on Wednesday and 12 million on Tuesday, he said.
Ubon Ratchathani, Yasothon, Roi Et and Si Sa Ket are still suffering floods in the aftermath of tropical storms Podul and Kajiki.
The storms brought flooding and landslides that affected more than 400,000 people across 32 provinces. A total of 34 people have been killed, according to authorities.
