Economy and Energy Minister Petar Dimitrov and Tunisian companies discussed options for natural gas deliveries from Tunisia to Bulgaria during a meeting earlier in the day, the ministry said in a statement.
There are significant gas deposits in the southern parts of Tunisia and the country plans to start exports, the ministry added, providing no further details.
Two major gas pipelines are expected to run across Bulgarian territory - the EU-backed Nabucco pipeline that would supply gas to Europe from the Caspian region and is aimed at decreasing the dependence of European gas supplies on Russian deliveries; and the South Stream gas pipeline, a project by Russia's gas giant Gazprom and Italy's oil and gas company Eni.
