U.S. Treasury Secretary Henry Paulson arrived in Moscow on Sunday for economic talks with Russia's top leaders that some observers say could help shift the focus of a sometimes frosty U.S.-Russia relationship towards the more productive areas of trade and investment, according to Reuters. Paulson, on his first trip to Russia since taking over as Treasury Secretary nearly two years ago, will have dinner with Russian Finance Minister Alexei Kudrin on Sunday night before closed-door meetings on Monday with new President Dmitry Medvedev and his predecessor, Prime Minister Vladimir Putin, the U.S. Treasury Department said. He also will meet with First Deputy Prime Minister Igor Shuvalov before flying to Berlin as part of a five-day trip that also will include meetings with German Chancellor Angela Merkel, European Central Bank chief Jean-Claude Trichet, British Prime Minister Gordon Brown and Finance Minister Alistair Darling.
