We should be clear that in terms of official policy statements, China uniformly expresses a clear and total commitment to its NFU policy. For example, a Chinese government website quotes Foreign Ministry Spokesperson Wang Wenbin at a November 2021 press conference as follows:
China abides by the policy of no-first-use of nuclear weapons at any
time and under any circumstances and undertakes unequivocally not to
use or threaten to use nuclear weapons against non-nuclear-weapon
states or nuclear-weapon-free zones unconditionally. No country will
be threatened by China's nuclear weapons so long as it does not use
nuclear weapons against China.
So in terms of official policy, the quoted statement is false. At best, this is a misrepresentation of arguments made by Chinese officials who are critical of the NFU. For a concise summary of such arguments see the relevant brief published by the Jamestown Foundation. Even if we assume that such critics have a strong influence on Chinese military policy (which is apparently not the case) I don't think they justify the statement with respect to India.
