Very urgent
use the passage below to answer the following question:

suppose the subject of another country were to come to england to trade, he would certainly be required to comply with the laws of england, then how much more does this apply to us of the celestial empire! now it is a fixed statute of this empire, that any native chinese who sells opium is punishable with death, and even he who merely smokes it, must not less die. pause and reflect for a moment: if you foreigners did not bring the opium hither, where should our chinese people get it to re-sell? it is you foreigners who involve our simple natives in the pit of death, and are they alone to be permitted to escape alive? —modern history sourcebook

based on the passage, what is commissioner lin's major goal?

to end the opium trade in china
to make china the equal of britain
to threaten foreigners in china
to enrich china through exports
