Not true, China and Pakistan are time tested friends, they helped us when ever we needed, more than 50% of our defence tech is from China or Chinese cooperation including things I can not mention. When in early 2010's when Pakistan was facing huge economic crisis with huge shortfall of electricity and no country was ready to invest in Pakistan, China came to rescue with huge 60 billion dollar CPEC and started energy projects which are the reason we see very less loadshading. I can go on and on in short there is no biggest ally of Pakistan in this world than China, not only ally but true friend.
