Western bosses withdraw from Russian economic conference

Around a dozen chief executives and chairmen of major U.S. and European corporations have pulled out of an economic conference in St Petersburg as pressure between Russia and the West grows over the crisis in Ukraine.
Eleven business leaders who were listed in late March as scheduled to attend the St. Petersburg International Economic Forum from May 22-24 are no longer on the program on the forum's website.
