I'm not really sure how much active trading there was between Afghanistan and neighbour countries until Taliban came in power. But no doubts that these activities is going to reduce. For my country this question doesn't matter because our trading with Afghanistan was close to zero.
market > your president or prime minister.
don't forget it, even if you believe it's your presidente dealing your salaries.
what are so called "drugs"? plants of the earth? natural plants of earth? others speak about the plants of the creation of god, so if your presidente or el premier want to fight the plants of the earth, and you wish to follow him in this path, may you be warned, you will be destroyed, and all you saw as immutable will become past... this is not a threat, but a fact.
your el presidente wants to stand between two individuals seeking a trade, for example in an extract of a plant of the creation of god, so you stand between the will of men, free will, informed consent, informed and trusted on the product exchanged, and the plants of the creation...
you may be trying to chew way to more, mortal...
Only regarding the poppy.
Poppy isn't just found in Afghanistan. With Afghanistan's relationship in the world, only those with ties to them can make transactions.
But China had already tied with them since the rarest element can only be found in Afghanistan, rare elements that shall be used for car batteries. So if the world will shift to renewable energy, everyone will have to trade with China which is the same as trading with Afghanistan.
The Mountain of gods and Giant Buddha is good for tourism in that country. If it weren't looted, there are more artifacts in this country that never had been shared to the world.
China relation with afghanistan date of time so old that even written is new to it... it's like asking when the Sioux met the Comanches... who knows... you know there were chinese silk in rome, and roman coins in china, before the Christ was born? you think it's hard to move from the atlantic to the pacific by foot and horses? you have become so weak, like all in the luxuries of sedentarisation... you just can't make the journey and back from in one day... patience with discovery along the way. and it's super easy to find the direction : look at where the sun raise or set, and leap frog... you will reach it, insh'allah.
your "shared" concept is funny... exploited? used a tourist income generating schemes? why not?
