Hun Sen, who has held power in Cambodia for more than three decades, last week ordered the rubber-stamp parliament to revise the law so that anyone who does not vote in the general election on July 23 will be barred from contesting any future elections.
At the last election in 2018, the Hun Sen's Cambodian People's Party (CPP) won all of the parliamentary seats, having scored 4.8 million votes out of the 6.9 million cast.
Hun Sen's administration has denied targeting opponents and says it is enforcing the law.
The election commission said earlier this month that anyone urging people not to vote would be fined or imprisoned.
The CPP will run virtually unopposed next month, after the election commission disqualified the sole opposition Candlelight Party from running, citing improper paperwork.
