American International Group said in a regulatory filing that it has withdrawn an application to sell group insurance in China because it needs to resolve issues including unauthorized sales in the Mainland by its Hong Kong-based agents, Reuters reported. AIG gave no further details on when the application would be resubmitted. AIG, which is being sued by US regulators over accounting irregularities, is the only foreign life insurer to operate in China without a local partner, thanks largely to the close ties between its former CEO Maurice Greenberg and Chinese officials.
