This pic was the genesis for the M20 Ridgway article (there's an attachment to the full piece somewhere in this thread). To sum up for those who don't wish to go searching for it, the Americans sent LAV-75s to China, where they were misused as TDs/light tanks due to heavy PLA armor losses. Based on combat reports from China indicating that the LAV-75 was unable to kill current Soviet MBTs with frontal shots, the US decided to up-gun its LAV-75s with 105mm rifled guns, and sent the first batch of upgraded LAV-75A2s to the PRC where they performed much better against Soviet armor. The LAV-75A2 became known as the M20 Ridgway, in US service.
