G20 agrees to address currencies as the summit ends
The G20 summit in South Korea has come to a close, with leaders of the world's major economies struggling to reach any substantial deal.
They did agree to avoid "competitive devaluation" of currencies but fell short of limiting trade deficits.
Tensions have been high, with America accusing China of keeping the value of its currency artificially low to make its exports cheap.
