So your point is... the Chinese should stand still and let be for their armour unit because they have 'all their base covered', while many of her neighbours are moving forward. See the point I am making?
Other forum members had answered. And it is with your mentality that, "I am the best now, so I should stand still" that I find appalling.
Ranting about been left behind when there isn't even a race is delusional. What threat, what neighbours are steaming ahead with tank development that's going to roll over the current PLA tank fleet?
The US Abrams M1A1 is slated to stay in service till 2021 and the M1A2 till 2050. So you would have the PLA refresh it's tank fleet? for what?
The Russians have stopped ordering T95s and are waiting for T99s to be ready for production
The answer is no one. Besides technically superior tanks lost at the Battle of the Bulge and at Kursk, end of the day soldiers win wars.
More to the point does the T99 need more armour, bigger gun, faster speed or more range to be competitive with the non-existent competition?
The Chinese Arms industry is opaque, development is not the same as production so do you have some top secret insight into their design process that tells you they've stopped development?
Finally, there's a DMZ and 1 million men of the North Korean People's Army between South Korea and the Chinese border so unless NK plan to wave them and their entire logistics train through or those superior SK tanks plan to swim, in which case the PLA needs better ships and subs not tanks, there's not going to be a tank battle with SK or for that matter Singapore or the Japanese.
My mentality is "I am happy with my BMW, I rather have a nicer house than a Rolls Royce"
