A Cultural-Historical foundation, The Link of Times was established by Russian businessman Viktor Vekselberg in February 2004. The core mission of the foundation is to repatriate cultural and historical pieces that have been taken out of Russia. Encouraging the United States and Russia, two seemingly polarized nations, to cooperate is incredibly important, especially in times of economic hardship. By assisting Russia in reclaiming emblems of its cultural heritage, this organization helps bridge the long existing gap between the former USSR and the United States.
