Drafting another Strategic Offensive Arms Treaty (START), as US President Donald Trump has proposed, will take a long time and be complex, Russian Presidential Spokesman Dmitry Peskov said at a news briefing on Washington's position the expiration of the current New START treaty will not be a problem. "You know the position voiced by President Trump – well, when this document expires, we'll make another, even better one," the Kremlin spokesman recalled. "Drafting a new one is long and complicated; there are many factors involved," Peskov noted. US President Donald Trump stated that he does not consider the expiration of the New Strategic Arms Reduction Treaty (New START) in February a problem, as he would prefer to negotiate a more favorable agreement. Washington, however, has strongly insisted that China's nuclear potential should be included in a future treaty.
