The Russian government is reigniting its push into the Arctic. Despite the challenging global economic environment, the Kremlin plans to build at least five new icebreakers, which, according to Prime Minister Mikhail Mishustin, will be used to further develop the Northern Sea Route across Russia’s Arctic coast. On Monday, Russia announcedthat it had started construction on the Leader project, the world’s most powerful nuclear-powered icebreaker, at the Zvezda shipyard in the Far East region. According to the government, the project is worth the expense because it will help make the Northern Sea Route accessible year-round and tap into the growing interest in the new transit corridor between Europe and Asia. But the Kremlin’s own interest in the Arctic is not only a result of the potential economic benefits; it’s also a matter of securing Russia’s eastern borders.
