Oh, you have access to accuracy evaluations of the ZPT-98? Do share. Or is it just based on your opinion that western guns are just superior? Hum?
The 125mm smoothbores on the current generation of PLA MBT are based upon the Russian 125mm smoothbore - both Western intelligence (such as BRIXMIS missions in East Germany, who were the first to crack some of the secrets about the T-64 as well as subsequent Soviet tanks armed with the 125mm smoothbore) as well as Israeli intelligence who had access to captured Syrian T-72s (and provided some to the US) tested the 125mm and discovered that is was, quote "more of a giant shotgun", unquote, devastating up to about a mile, but suffering dispersal beyond 1800 metres.
On our own ChinaDefense.com site on the ZTZ-99 MBT, the article states that the ZPT-98 is believed to be a version of the Russian 125mmm smoothbore. The ZPT-98 has a muzzle velocity of 1780 m/s (compared to Western analysis of the Soviet 125mm which was found to have a muzzle velocity of 1800 m/s) with sabot rounds, and the ZPT-98 also fires the same Refleks AT-11 gun-launched ATGM as the Soviet 125mm. Clearly, they are besically the same gun and share the same performance. PM DongFeng about this if you doubt it.
As for Western 105mm/120mm guns, firing sabot rounds from about 1400 m/s to about 1700m/s, the 105mm was rumoured to be able to of taking out targets from a stationary M-60 A3 at 5,000 metres (try James Bolgers' Dragons At War - it's about the National Training Center at Ft. Irwin California), and the published reports of the M-1 A1 taking out targets in the Gulf War while on the move at 3,200 metres (also while stationary too) with 120mm gun (try, amongst others, the General's War by Michael R. Gordon and LtGen. Bernard B. Trainor (USMC ret.). Samuel Katz claims (from Israeli sources) that the Merkava can hit targets with sabot at 6,950 m, (whether that is with consistency, he does not say).
In any case, the ZPT-98, which is a Chinese version of the Soviet 125mmm smoothbore, does not have an equivalent armour-piercing shell accuracy at range performance to that of Western tank guns. That is why the Russians have resorted to tank-gun-launched ATGMs since the 1980's.
