Thai Prime Minister Anutin Charnvirakul wrote on Facebook that Thailand would "continue military actions until we no longer feel any harm or threats to our land and people."
Trump, who brokered a ceasefire in the long-running border dispute in October, spoke to Anutin and Cambodian premier Hun Manet on Friday, and said they had agreed to "cease all shooting", News.Az reports, citing Reuters.
Neither of them mentioned any agreement in statements after their calls with Trump, and Anutin said there was no ceasefire.
"I want to make it clear. Our actions this morning already spoke," Anutin said.
The White House did not immediately respond to a request for comment on the continued fighting.
Hun Manet, in a statement on Saturday on Facebook, said Cambodia continues to seek a peaceful resolution of disputes in line with the October agreement.
