Vladimir Putin certainly knows how the West views his actions in Ukraine. Sanctions have been in place against Russia for months. There is talk of toughening them. At the G20 meeting in Australia he was rebuked by Angela Merkel, Stephen Harper and other leaders, before flying home early. But are sanctions having any real effect on the Russian president? Are they likely to force him to change course in Ukraine? We hear from a top Moscow economist Natalia Orlova, a Putin loyalist in Vladivostok, veteran European diplomat Sir Robert Cooper and Fyodor Lukyanov, editor of Russia in Global Affairs and a close Putin-watcher.
