Absolutely this.
China is still friends with Pakistan but not fond of this specific adminstration. Also Pakistan falling out with the Afghan Taliban has made them appear confusing to the Chinese which is true this admin is completely messed up instead of befriending the Afghans and expanding trade routes Pakistan started beefing with Kabul over irrelevant TTP militias and they tried to force that on Kabul... China suspects US hands or Pakistan becoming a US lackey or servant. China actully improved ties with Kabul. China wants Kabul-Islambad as bulwark against India.
But Pakistan is breaking rank.
Pakistani businesses have lost billions of dollars which goes to show Pakistani military do not care about the private sector whatsoever otherwise they wouldn´t have closed all the border corridors to Afghanistan which leads to central asia if they did. Now Afghanistan has connected their economy to other countries such as Iran, Uzbekistan, China etc etc they will benefit from it.. Pakistan starved itself from billions of dollars, due to some fuking irrelevant populist gov´t reactions that will only be remember as the trend of the month but nothing more
