That is just diplo-speak for 'discrimination, double standards and hypocrisy'.
If you are to use this argument, then every country discriminated against by the US and other world powers should set up black market operations and trade with every other nation in similar situations, to obtain technology each may want, and everything is justifiable under 'interests'.
If on the other hand you are to argue that 'non-proliferation', international agreements, treaties are to be honored and international behavior is to be governed by certain standards, then you must have a set of standards that applies to everyone, not just those one nation prefers over another. Otherwise you yourself have opened the door to ignoring agreements, treaties and set 'standards of international behavior', as the US has done by arbitrarily lobbying to grant India an exemption from the NSG in violation of its guidelines, instead of introducing a standard criteria that all nations would have to meet to qualify for exemptions.
