ChangZheng 6 (Long March 6) Launch Vehiclehttp://www.sinodefence.com/space/launcher/changzheng6.aspChangZheng 6 (CZ-6, or Long March -6 in its translation) is a liquid-propellant, small-load space launch vehicle (SLV) currently developed by China Academy of Launch Vehicle Technology (CALT). The launch vehicle is based on the 2.25m-diameter core stage, which has been developed as a strap-on booster for the CZ-5 family of SLV. The core stage consists of a 120t-thrust YF-100 engine that burns oxygen and kerosene (LOX/Kerosene) propellant, which causes less pollution compared to the UDMH/N2O4 (nitrogen tetroxide) propellant currently in use.The ChangZheng 6 is designed for small-load launch missions, with a sun-synchronous orbit (SSO) capability of 500kg. The first launch of ChangZheng 6 is scheduled in 2010.Last update: 20 February 2009
Presumably this is a replacement for the KT-1.

1.CZ-6 is not developed by CALT but SAST(Shanghai Academy of Space Technology).
2.The launch vehicle is based on the 3.35m-diameter core stage but not 2.25m-diameter.
I doubt it because we've already seen mentions of CZ-2F/H using the 3.35 m core stage with YF-100 engines. Also, if the payload mass is not misquoted I can't imagine a 3.35 m vehicle with such a low capacity.
Only one YF-100 engine in the the 3.35 m core stage of the small launch vehicle, the upper stage is 2.25 m diameter with a 15 tonne thrust YF-115 engine. the payload mass is appropriate with thrust。
Changzheng 6 is the PRC’s new generation liquid-propellant, small-load launch vehicle, currently being developed by the Shanghai Academy of Spaceflight Technology (SAST). The launch vehicle is designed to send at least 500kg payload into the Sun Synchronous Orbit (SSO) of 700km.The launch vehicle is based on a 3.35m diameter core stage, which consists of a single 120t-thrust YF-100 rocket engine. The second stage uses a single 15t-thrust YF-115 engine. Both engines burn an oxygen and kerosene (LOX/Kerosene) propellant. The third stage is 2.25m in diameter and consists of four 1kN-thrust rocket motors.Last update: 1 Nov 2010
