Lithuania's natural gas supply and trade company Lietuvos Duju Tiekimas (Lithuanian Gas Supply, or LDT), which buys liquefied natural gas (LNG) from the United States, says that it had signed a supply contract with Latvenergo, Latvia's largest gas consumer, adding that it expected to gain a 10 per cent market share in the neighbouring market this year and to become its second-biggest gas supplier after Latvijas Gaze.
