The U.S. Securities and Exchange Commission is examining the extent to which JPMorgan executives at its headquarters were involved in overseas hiring, the report said.

A JPMorgan executive in Asia alerted the bank's New York officials in 2011 of concerns that the bank had hired a son or daughter of a senior Chinese government official, a recruitment that helped it win an investment-banking assignment, according to company emails reviewed by the Journal.

JPMorgan officials proposed changes to its hiring practices in Asia and the changes formed a part of a set of anticorruption measures approved by its board directors on the bank's audit committee in late 2011, according to the report.

Chief Executive Jamie Dimon also knew of the anticorruption measures as they were unveiled, according to the report.

U.S. authorities have not accused the bank of any wrongdoings yet.

A JPMorgan spokesman declined to comment on the story.
