There are 3 major space technologies that India is currently behind China.
No1. A mature medium launch vehicle that is capable of lofting between 2,000 to 20,000kg to LEO.
India:
Current GSLV can only carry 5t to LEO and 2t to GTO
(only 6 launch and less than 50% success rate is a disaster for the rocket! )
GSLV MK3,currently under development(2013?), is only boost payload to 10t to LEO and 5t to GTO
China:
Current LM2f/g can carry 11t to LEO and LM3b 6t to GTO
However, those 2 rockets are very mature and have a 90%+ success rate! (more than 40
launch combine in last 20 years)
LM5, currently under development(2014?), boost payload to 25t to LEO and 15 to GTO.
NO2. Manned spaceflight!
India: None
Missing/Unmature technology: Atmospheric reentry(1 test so far for India if i'm not wrong, Orbital module(life system),Ground monitoring(guiding system), and A mutual launch vehicle that can sent 10t to LEO.
China: 5 unmanned test flight, 4 manned spaceflight which send 9 people into space.
NO3. Space station
India: None
Missing/Unmature technology: Space walk(EVA), Space docking and A mutual launch vehicle that can carry at least 20t to LEO.
China: 1 space lab. 1 station(Plan:2020?)
Missing/Unmature technology: EVA(1 test) , launch vehicle is in development(2014?)
So if China stop everything at this moment. India need at least a 5-10years(with foreign help)
or 10-20years (without foreign help)to catch up.
There are many other area where China is ahead of India, but aboves are the major technologies.
Of course, India have few space technologies that ahead of china as well. I will list a few when I have time.
