West worried by China-Pakistan atomic ties?

Western states pressured China at closed-door talks last week to address concerns about its plans to expand a nuclear power plant in Pakistan and provide more information, but were rebuffed, two diplomatic sources said on Wednesday. Beijing's atomic relations with Islamabad have caused unease in Washington, Delhi and other capitals.
"A number of countries asked questions and expressed concerns," said one official, speaking about the annual plenary session of the 46-nation Nuclear Suppliers Group (NSG), held on June 21-22 in the US city of Seattle. But China showed no sign of reconsidering its position on building two more reactors at the Chashma nuclear power complex, the official and another source said.
