Thailand closed its border with Cambodia on Monday. Tourists cannot go from Thailand to Cambodia. This is because the two countries have a problem at the border.

Two countries had a fight on May 28. One soldier died. Now, they are not friends. They said they would stop fighting, but they are still causing problems.

Thailand's leader said they will check people more at the borders. Only students, sick people, and people who need to buy important things can go in or out of Thailand.

She said they wanted to stop people from going to casinos in Cambodia. But it looked like all visitors could not go.

The army in Thailand closed the border with Cambodia. Only people who really need to can cross.

Cambodia stopped using some internet from Thailand. It also stopped getting power and gas from Thailand. This happened because of a problem at the border. Before this, Cambodia got 30% of its gas from Thailand.

Paetongtarn said Thailand will stop things that help scams in Cambodia. Thailand will also work with other countries to stop online crime in Southeast Asia.

Thailand stopped electricity and internet in some towns. These towns were near the border. They did this to stop bad online activities from Myanmar.

In April, a U.N. report said Cambodia is a place for online scams. People there trick others with fake love, bad investments, and illegal games.

Some people are angry with Paetongtarn. They think she is too kind to Cambodia. These people are right-wing. They do not like her father, Thaksin. He was the Prime Minister before.

Last week, Paetongtarn and Hun Sen talked on the phone. Hun Sen was the leader of Cambodia for a long time. Many people are angry about this call. They want Paetongtarn to leave her job.

Some people were not happy with her. They said she made Thailand look weak. She called an army leader her "enemy." Some groups will meet this week. They want her to leave her job.
