Clinton arrives in Moscow to sign a nuclear agreement.

MOSCOW - U.S. Secretary of State Hillary Clinton arrives in Russia on Thursday for crucial talks on a new agreement on nuclear disarmament between the former adversaries of the Cold War. Effects of the Strategic arms reduction agreements of 1991, ended in December, and the negotiators were unable to agree a new contract. This prevented both powers "restart" partly damaged relationships. The official reason for the two-day visit, Clinton - four-Middle East summit. But officials on both sides confirmed that Secretary of State to negotiate a new agreement with its Russian counterpart, Sergei Lavrov. The American President Barack Obama and the head of Russia Dmitry Medvedev met to sign a new agreement by the end of 2009, to significantly reduce nuclear arsenals, but the negotiations in Geneva have stalled because of strong disagreements. Russian and American officials say that the remaining problems are technical and relate to the fact that the final document will consist of hundreds of pages and must be translated into Russian and English languages, without inconsistencies. "We never talked about any differences. The usual process of negotiations is under way. This is a very extensive document," said the Russian Foreign Ministry spokesman Andrei Nesterenko. Last week the New York Times reported that Obama was so disappointed that Medvedev is bound by an agreement on disarmament with the debate over U.S. plans to install missile defense facilities in Eastern Europe. Moscow was outraged statement Romania in January that it intends to establish the leading elements of U.S. missile shield on its territory, reports The New York Times. Military analyst Pavel Felgenhauer said the stumbling block was Russia's demand to abandon plans for missile defense, which the U.S. Senate refuses to perform when it comes to ratification of the agreement. "They are trying to find a formula which can satisfy both sides," said Feldgenhauer, the military commentator of the newspaper Novaya Gazeta. "The United States would sign an agreement quickly in order to improve the atmosphere. But this is not obtained and instead renew the relationship, new problems," he said. In his last telephone conversation on Saturday, the two presidents expressed their satisfaction with the "perfect state of preparation of" a new contract and concluded that the final date for the talks might already be scheduled, according to the Kremlin. Some reports said that both sides want to complete the negotiations before the United States Summit on Nuclear Safety on April 12-13. On Tuesday, daily Russian newspaper Kommersant reported that the Philippines offered its territory to sign a new agreement and confirmation of its status as an equivalent partner with the East and the West. "This will be an important milestone. It is one of the key points reboot relations," said former U.S. Ambassador to Russia James Collins, director of the Russia program at the Carnegie Center. US-Russia relations have ceased to be trustees under President George Bush, and the signing of a new nuclear agreement will be evidence of a new stage in relations between the two countries. Signed in 1991, the START agreements led to a tremendous reduction in U.S. and Russian nuclear arsenals, and ensure the arrangements for monitoring compliance with agreements. The contract was supposed to contribute to a lasting peaceful relations between the two former adversaries of the Cold War. The probability of signing a new agreement became apparent in July, when Obama and Medvedev agreed to reduce the number of warheads on both sides to 1500-1675 units. The United States report that they currently have approximately 2,200 nuclear warheads, while Russia's is believed to have about 3000 units.
