We need to increase yields up to a point to meet our own needs before we export to the Chinese market. Ideally this would be the restrictions we put on this, but the very export of cattle will (if promoted by the government) lead to investors going into breeding more cattle.
Considering the strategic nature of our food supply, we should tie this program into a one that modernizes the entire meats and diary cow industry.
As for pasture land, should should look at how other countries feed their cattle and increasing the amount of grazing land we have through revitalizing marginal land.
We have one of the worlds lowest yields in our agricultural and meat and diary industries, with a viable and growing export market like China, these industries will hopefully attract the kind of investment (such as billions from overseas Pakistanis instead of into real estate) that will produce more for the local market and the export market.
This is all about honest and knowledgeable management and introducing the right equipment and knowledge.
Taking cattle out of local food supply without finding a way to increase the local food supply will cause massive price hikes and undo burden on our people trying to afford a sufficient amount of protein in their diets
The government needs to tread carefully here, continuous food price increases could be their undoing.
