April 13 (Bloomberg) — Daniel Rosen, principal of the Rhodium Group in New York, talks with Bloomberg’s Susan Li about US calls for China to allow its currency to appreciate and the impact a stronger yuan would have on the mainland’s economy. US President Barack Obama met yesterday with Chinese President Hu Jintao and reaffirmed his view that it is “important” for China to move toward a “more market-oriented exchange rate,” a White House aide said. Rosen, speaking from New York, also talked about the international gathering aimed at containing the spread of nuclear material. (Source: Bloomberg)
