Venezuela says it will close its border with Colombia at night from Monday, to try to stop large-scale smuggling of petrol and food.
The government says that tonnes of goods - produced in Venezuela and heavily subsidised - are sold in Colombia at much higher prices.There's a real shocker.
The 2,200km-long (1,360 miles) border will be closed between 22:00 local time and 05:00 every night.
Cargo vehicles, including vans and lorries, will be banned from crossing from Venezuela to Colombia between 18:00 and 05:00.That'll stop 'em, sure.
The cross-border smuggling is also a problem for Colombia, with a big loss in taxes and complaints of unfair competition by local businessmen.
The profits are often used to finance drug gangs and left-wing guerrillas, says the BBC's Arturo Wallace in Bogota.
More than 40 million litres of petrol and 21,000 tonnes of food have been seized so far this year.At no cost to the citizens?
