Laos and Vietnam are to complete the demarcation of their 2,000-kilometre border by June, state media reported Tuesday.
The project to define the partially disputed border was launched in 2008 and has put down 763 markers, leaving 72 to go by the June deadline, the state-run daily said.
"The project aims to create a shared border of peace, friendship and sustainable development and will also enhance the special relationship, solidarity and comprehensive cooperation between Laos and Vietnam," it said.
Laos and Vietnam have been close allies since the Indochina War, which pitted the United States military against the two countries' communist forces.
