"Contracts with Japanese enterprises must be honored," the unnamed high-ranking official in the Japanese Foreign Ministry was quoted as saying in an article published on Saturday.
Russian President Vladimir Putin signed a decree on Thursday that allows Russia to create a new project operator that will take charge of Sakhalin-2 from Sakhalin Energy Investment Co. Russia's Gazprom will keep a majority stake of 50% plus one share. Shell has already promised to sell its 27.5% stake, while Mitsui and Mitsubishi reportedly plan to hold on to their 12.5% and 10% stakes respectively.
Deputy Chief Cabinet Secretary Seiji Kihara said on Friday that the government was studying the contents of the decree. He told a briefing that interests of Japanese companies in the project in Russia's far east should be respected. Sakhalin-2 accounts for 9% of Japan's LNG imports.
