Thailand closed its land border on Monday. Tourists cannot go to Cambodia. This is because Thailand and Cambodia have a border problem.

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

The leader said Thailand will check people more at the border. Tourists cannot leave. Only students, sick people, and people who need 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 Thai army closed the border with Cambodia. Only people with important reasons can cross.

Cambodia and Thailand have a problem. Cambodia stopped using some internet from Thailand. They also stopped buying power and gas from Thailand. Before, Cambodia bought a lot of gas from Thailand.

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

This year, Thailand stopped power, internet, and gas in towns near Myanmar. They did this to stop bad online scams.

In April, a U.N. report said Cambodia is a place for bad online tricks. People work there to cheat others. They pretend to like people, offer fake ways to get money, or play bad games to take money.

Some people don't like Paetongtarn. They think she is too kind to Cambodia. These people are often right-wing. They also don't like her father, Thaksin Shinawatra.

Last week, a phone call was heard. It was between Paetongtarn and Hun Sen. Hun Sen was the leader of Cambodia for a long time. Many people were angry about the call. They wanted Paetongtarn to stop her job.

Some people said she tried to please Hun Sen. He was her father's old friend. They said she made Thailand seem weak. She called a Thai army leader "an enemy." Some groups will meet this week. They want her to leave her job.
