Selling items on non-muslims country store that mixing haram and halal items
Assalaamu 'Alaikum. 
I'm a businessman that had a plan to open export import foreign business. Now i had a problems regarding exporting to non-muslims country. Let's say i had 3 tons of vanilla extract i want to distribute to New Zealand. I had an affiliation which connects me to a lot of supermarket and minimarket in that country. But as you may notice their supermarket are selling pork and khamr inside them. Is it permissible for me to sell my halal product into supermarket in non-muslims country that also sells haram product?
Please provide daleel for these matter.
JazakAllah Khair

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Shariah permits us to deal with non-Muslims. It is obvious non-Muslims do not deal only in Halal. We are not responsible for their haram dealings and their source of income. If you sell halal items to non-Muslims, your income will be Halal.[i]
