In a Buenos Aires Times interview, Dominique Strauss-Kahn stated the US "worked against reforms which I tried to put through and which would have considerably increased the share of emerging markets".

This assertion is FALSE! The US then led the way on IMF quota reforms.

The Bush/Obama Admins views on quota reform were the same.

The US called for modernizing IMF shares and boosting dynamic EMs' shares in 2005. In 2006/08, a two stage reform was launched.

The US supported EMs/LICs. It backed a GDP centered quota formula, including an element of PPP, as called for by BRICs. The US volunteered to forgo any increase in its voting power due to a higher GDP weight. The US supported a tripling in basic votes for LICs.

The US called for further quota reform to boost dynamic emerging markets in 2009. Due to a strong US push, the Sept 09 G20 Pittsburgh Summit called for a shift of at least 5% of quota share to dynamic EMs. This was pushed through a year later by the time of the Seoul Summit.

The US in 2010 called for reducing 2 European Board Chairs to cut EU overrepresentation. This is not yet completed.
Between 06/10 about 10% of quota share was shifted.
Throughout, Europe and Japan dragged their feet.

The reforms resulted from US leadership and the US push.
