Hungary will seek to increase the amount of gas it receives from Russia at talks with President Vladimir Putin early in February, Prime Minister Viktor Orban said on Friday.
Hungary, a member of the European Union and NATO, agreed a new long-term gas supply agreement with Russia's Gazprom in August.
Mr Orban, who faces what is expected to be a close-fought election on April 3, has dismissed calls from a unified opposition to cancel his visit to Moscow, scheduled for Tuesday.
“I would like to increase the amount of gas to be delivered ... from the levels agreed in the Russian-Hungarian gas contract,” Mr Orban told public radio.
The 15-year agreement, which delivers 4.5 billion cubic metres of natural gas per year to Hungary on routes avoiding neighbouring Ukraine, took effect in October with an option to modify purchased quantities after 10 years.
Hungary's gas reserves were 43 percent filled, based on Energy and Public Utility Regulatory Authority (MEKH) data from January 15. It said that, combined with expected further imports, it would cover 90 percent of Hungary's expected remaining winter gas needs.
