Dutch international heavy lift and haulage contractor Mammoet has frozen all new work and investment in Russia and issued a statement regarding its activities in the region. It operates from two locations in the Russia - Mammoet Rus with an office in Moscow and Mammoet Sakhalin in the far south east of the country, near Japan. Putin also signed off on a proposal to allow Mammoet to sell its Russian subsidiary to a China-registered player.
