He was also ordered to appear before Judge Frazier on Sept. 30 for a bond status hearing. Gyetvay did not immediately respond to a Reuters request for comment. Novatek declined to comment beyond its earlier statement. New Jersey-born Gyetvay, 64, moved to Russia in 1995, working as a partner at PwC Global Energy. Russian President Vladimir Putin granted him a Russian passport in 2019, when he was at Novatek, in a move seen as potentially helping the U.S. national bypass some U.S. sanctions restrictions. A Kremlin spokesperson said Russian diplomats were ready to provide legal assistance to Gyetvay in the United States. "Because this individual is also a citizen of the Russian Federation, if I understand this correctly, he has dual citizenship, of course we are interested in his future and the circumstances of the case," Dmitry Peskov told a conference call. Novatek commissioned Yamal LNG, its first LNG plant in the Arctic, in 2017. The project challenges state-controlled Gazprom (GAZP.MM), which has a monopoly on Russian gas via pipeline. It wants to build more LNG plants in the Russian Arctic and is in the middle of efforts to attract more than 9 billion euros ($11 billion) for its Arctic LNG 2 project, to be raised from the Russian banks, Japan, China and others. read more ($1 = 0.8522 euros)
