Dominique Strauss-Kahn, the head of the International Monetary Fund, on Friday reiterated his criticism of China’s “undervalued” currency, but said reforms to exchange rate policies were part of wider moves to create more balanced global growth.

Speaking at the opening of the World Bank and IMF annual meetings in Istanbul, Mr Strauss-Kahn and Robert Zoellick, the bank’s president, called for the world to continue co-operating on international economic issues even as the economic and financial crisis fades.
