Yes, the TP2000 should carry up to 2 tons of cargo.
Although, my point above is how China should rapidly increase the tactical airfliting capabilities of the PLAAF as soon as possible by fielding more and larger UTPs, so that the PLAAF is at least on par with the VVS in that regard.
The geopolitical tension in the Western Pacific is heating up, and I do expect that the Taiwan scenario would not be going easy for the PLAAF at all.
To be honest, the immense challenges that would face the military logistical chains of the PLA just kinda scares the shit out of me.
Moreover, making sure your logistics are secure and stable is the backbone for any successful military operation anywhere in the world. You don't win a war on empty stomaches and empty magazines.
