Thailand closed its land border on Monday. Tourists cannot go to Cambodia. Thailand and Cambodia have a problem at their border.

The countries had a fight on May 28. One soldier died. Now, the countries don't like each other. They said they will stop fighting, but they are still angry.

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

She said the rules were to stop people from going to casinos in Cambodia. But it looked like all visitors would be stopped.

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

Cambodia stopped using some Thai internet. They also stopped buying power and gas from Thailand. This happened because of a problem at the border. Before this, Cambodia bought 30% of its gas from Thailand.

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

Thailand stopped electricity and internet in some towns in Myanmar. They wanted to stop bad online activities there.

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 nice to Cambodia. These people are right-wing. They do not like her father, Thaksin. He was a leader before.

Last week, Paetongtarn and Hun Sen talked on the phone. Hun Sen was the leader of Cambodia for a long time. People are very angry and want Paetongtarn to leave her job.

Some people were angry. They thought she was too friendly with Hun Sen. He was her father's friend. They said she made Thailand look weak. She called a Thai army leader her "enemy." Some groups will meet this week. They want her to stop her job.
