Nothing but your typical Indian bluster and wishful thinking.
Chinese jets do not need to carry anything like a full weapons load for air dominance missions in the boarder areas.
For deep strike missions against targets deep in India, that would indeed be a problem, but not for air superiority over the boarder regions.
And even for strike missions, PLAAF jets could always take off with the desired weapons load and minimal fuel and top up from a tanker before heading into the combat zones.
Besides, Indian air bases within operating range of the boarder will get saturate attacked with cruise and maybe even ballistic missiles during the opening stages of any war. And any IAF planes coming close to the boarder will have to run the gauntlet of multiple layers of PLA SAMs and AAA.
In the future, if China really wanted to fight India, it can easily adapt the EMAL technology it is developing for its carriers for use on high altitude runways as a means of boosting the take-off load of its warplanes.
