Russia said that talks with the United States on nuclear arms reductions have been constructive, but suggests a summit next month may not bring a new deal, according to AP. Talks on an arms reduction deal to replace the 1991 START treaty are a keystone of efforts to improve troubled Russian-American ties. Russian Foreign Ministry spokesman Andrei Nesterenko says the talks have been held in a «constructive and businesslike» atmosphere. He said Thursday that Presidents Barack Obama and Dmitry Medvedev will likely be able to «announce intermediate results» at the summit in early July, suggesting an actual deal is more likely to come later. START expires in December. Nesterenko says the next round of talks is next week in Geneva.
