Phead, why do you think so? Korea is not ideal tank country with a mountain range on the east side, it does not have much room to maneuver with the whole Korean peninsula being 100 km wide. Definitely not the deserts of the middle east, or the permafrost of Siberia. or the great american plains.The latest Chinese MBT tank will probably be fielded in Korea, probably against South Korean-US tanks on the Korean peninsula.
What would face down SK and American tanks in Korea will likely be advanced antitank missiles and munition.
Where the Type 99 will be employed and is currently stationed would be the great northern Chinese flatland in Manchuria and inner Mongolia. If central asia some how miraculously starts rearming, it will likely be deployed in xinjang and tibet.
