Donald Trump has pursued business deals in Russia since 1987, and has sometimes traveled there to explore potential business opportunities. In 1996, Trump trademark applications were submitted for potential Russian real estate development deals. Trump, his children, and his partners have repeatedly visited Russia, connecting with real estate developers and Russian government officials to explore joint venture opportunities. Trump was never able to successfully conclude any real estate deals in Russia. However, individual Russians have invested heavily in Trump properties, and, following Trump's bankruptcies in the 1990s, he borrowed money from Russian sources. In 2008 his son Donald Trump Jr. said that Russia was an important source of money for the Trump businesses.
