JPMorgan Chase & Co said on Monday it had received approval and license to underwrite corporate bonds in China's interbank bond market, making it the first U.S.-headquartered bank to do so. The license enables JPMorgan to underwrite debt financing instruments issued by non-financial entities, including commercial papers, medium-term notes and other instruments approved by regulators, it said. The license was granted by the National Association of Financial Market Institutional Investors (NAFMII), which oversees the Chinese interbank bond market, said a statement issued by JPMorgan.
