"It is very likely that we could use certain swap mechanisms. For example, gas from Norway would travel physically, while Qatar's gas would go to other customers in Asia," he told the Žinių Radijas radio station on Tuesday.
Udrėnas said that Lithuania is an interesting customer to Qatar's gas suppliers, because that would help them diversify their sales portfolio.
"The distance to Lithuania is relatively short. By the way, Poland has also signed a contract with Qatar for gas supply to the terminal they are building in Swinoujscie," he said.
President Grybauskaitė is to pay a visit to Qatar on 29 April, accompanied by Energy Minister Arvydas Sekmokas and Rokas Masiulis, CEO of Klaipėdos Nafta (Klaipėda Oil), which is implementing Lithuania's LNG terminal project.
The President's Office said last week that the prospects for ensuring cheaper gas supply to Lithuania would be discuss during the visit. Sekmokas has told BNS that potential gas supplies for Lithuania's LNG terminal include the United States, Norway and Arab countries.
Klaipėdos Nafta plans launching a tender this year for the supply of gas to the LNG terminal in Klaipėda and expects to sign a gas supply contract in the second half of the year. The terminal is planned to be launched in late 2014.
