Russia has faced rebukes from Western leaders about its role in the Ukraine crisis at the G20 summit in Brisbane, Australia. Canadian Prime Minister Stephen Harper told Russian President Vladimir Putin that he needs to get out of Ukraine. US President Barack Obama said, Moscow's aggression in Ukraine is a threat to the world, while the UK threatened more sanctions unless Russia stopped destabilising its neighbour.

The two day summit in Brisbane is focusing on promoting economic growth. World leaders are expected to elaborate on plans agreed by G20 Finance Ministers in February to boost global growth by two percent in five years.

However, yesterday, the first of the two day summit was dominated by Ukraine, where pro-Russian separatists have been fighting government forces in eastern regions. Ukraine and its Western allies have accused Russia of sending military forces across the border, something the Kremlin denies.
