PHNOM PENH, Cambodia (AP) -- Cambodia's government on Tuesday accused Thailand of escalating border tensions by imposing new restrictions that have blocked almost all land crossings, especially for tourists heading into Cambodia.

Relations between the neighbors have deteriorated following an armed confrontation on May 28 in which one Cambodian soldier was killed in a relatively small, contested territory along their border. While the two sides have agreed to de-escalate their dispute, they have continued to implement or threaten measures that have kept tensions high.

The Thai army on Monday imposed heightened restrictions at border checkpoints with Cambodia following an order from Prime Minister Paetongtarn Shinawatra to allow only students, medical patients and others with essential needs to enter or leave Thailand. That also makes it impossible for thousands of tourists to cross between the two countries.

Pen Bona, a spokesperson of the Cambodian government, said Tuesday that Cambodia has committed to resolve the conflict through diplomatic channels, but tensions have soared because of Thailand's actions.

"The Cambodian government has already stated that we will not initiate any border closure," and that it will also lift restrictions if Thailand does so first, he said.

Cambodia has boycotted some Thai internet services, banned Thai fruits and vegetables, and blocked electricity and fuel supplies from Thailand in response to the border dispute. Prior to the boycott, Cambodia imported 30% of its gasoline and other fuel from Thailand.

Cambodia's Prime Minister Hun Manet on Monday visited troops at the border and a temporary shelter for thousands of civilians who were evacuated from the area. He said that while Cambodia doesn't want war, "we cannot stand by and let us be abused."

In addition to border restrictions, Paetongtarn also announced measures targeting online scam operations in Cambodia. They include blocking exports that could facilitate such activities in Cambodia and coordination with other countries and international agencies to crack down on cybercrime based in Southeast Asia.

Pen Bona said that while he recognized that Cambodia "is being exploited by online scammers," many such operations are also based in Thailand.

"This is a very shameful thing that is happening in Thailand, but they are trying to divert the story from Thailand to Cambodia," he said.

Thailand earlier this year implemented measures to crack down on online scam operations in neighboring Myanmar, severing electricity, internet and gas supplies to border towns where the syndicates were based.
