* Bank of Canada Governor says in era where will probably be some changes to trade architecture, welcomes "dusting off" of NAFTA
MOSCOW, March 21 Russia's biggest bank Sberbank is looking "very actively" at options for a quick exit from Ukraine, the bank's Chief Executive German Gref said on Tuesday.
Gref also told reporters that Sberbank's loan-loss provisions in Ukraine made up around 70 percent of its potential losses.
Ukraine recently decided to impose more sanctions on Sberbank and other Russian state-owned banks operating in Ukraine - part of a broader flare-up in tensions linked to separatist regions of eastern Ukraine which are backed by Russia.
