Ex-leader Hun Sen made good on his threat to block imports after Thailand maintained border curbs, urging Cambodian migrants to return home

The Thai and Cambodian armies both said they acted in self-defence.

Thailand has imposed border restrictions with Cambodia in recent days, while Cambodia banned Thai dramas from television and cinemas, closed a popular border checkpoint, and cut internet bandwidth from Thailand.

Cambodian authorities said on Tuesday that their Thai counterparts were still imposing the border restrictions and Hun Sen’s ultimatum had taken effect.
