By Maria Kiselyova MOSCOW (Reuters) – Russia has proposed that Apple Inc and SAP hand the government access to their source code to make sure their widely used products are not tools for spying on state institutions. The suggestion that two of the worlds flagship technology companies disclose some of their most sensitive business secrets comes as the United States and Europe debate their most severe sanctions yet against Russia for its role in Ukraine. The European Union reached agreement on Tuesday on its first broad economic sanctions, marking a new phase in the biggest confrontation between Moscow and the West since the Cold War. The Russian proposal was voiced last week when Communications Minister Nikolai Nikiforov met Apples general manager in Russia, Peter Engrob Nielsen, and SAPs Russian managing director, Vyacheslav Orekhov, the Communications Ministry said in a statement.
