Gazprom has already stored up to 700 million cubic meters of gas in Hungary since last year.
He also said Hungary would not sell any of its gas storage facilities to Russia.
Szijjarto said Hungary wanted to tap Russian gas via Turkey as well, and expected intensifying talks with Turkey, Greece, Macedonia and Serbia about a potential new pipeline that could follow that route to central Europe.
Azerbaijan remained another possible gas source, he said. Regional cross-border interconnectors along a north-south corridor and possible imports from Croatia via a planned liquefied natural gas (LNG) terminal there were also desirable, he added.
