Central and West African states are looking at moving their reserves out of France and unifying their currencies as one called the "Eco". The CFA Franc is a multi-nation currency created in 1945 by order of Charles de Gaulle, when most of West Africa was still under direct French colonial rule. The currency union deposits 50% of their reserves with the French Treasury, and in return have a guarantee of convertibility of CFA Francs into Euros. Due to the strong ratio of foreign currency reserves to issued currency, this third party guarantee - African leaders feel - is no longer necessary.
While they will distribute the reserves to multiple banks outside the French Treasury, including the United States, one of the possible destinations is China. France has a long and complicated history with former colonies. As a numismatist I can tell you the Paris Mint produces coins for a wide array of countries to this day.
