An unknown seven roadwheeled hull mounted with a special ZTZ-99A turret that has the long L/54 125mm cannon.
Given the crappy ass quality of the video, it's likely from quite some while ago given the long gun was rejected during Type 99A's development hence probably unrelated to the Type 100 or heavy next gen MBT despite looking kind of similar. IMO, probably just a engine testbed or rejected prototype.
