Is 6 month passport validity required for transit through China?

My passport will expire in the next 2 months. I am an Indian national traveling from India to Los Angeles (USA) while transiting through Guangzhou (China). The transit stop is only for 2 hours and I will not be leaving the airport.USA allows for entry and exit up to the passport expiry as long as visa is valid. Will I have any problem at Guangzhou airport in the transit through china with my passport expiring before the 6 month period mentioned above.
