The massive Marriott hacking that the hotel chain revealed this month could become part of the trade negotiations between the U.S. and China.

The data breach lasted four years, and the intruders stole information about 500 million customers. On Tuesday, The New York Times reported that investigators had traced the hack back to the Chinese government, calling it part of a broader intelligence-gathering operation. Reuters had previously reported Chinese involvement.
