What was a cause of the european interest in goods from asia?

The European began to take interest in goods from Asia because of the crusades.                                                                                                                                          

Explanation:

The crusade helped European to gain interest in goods and new products from Asia that were new to them. Crusades introduced spices, silk, carpets, textiles, also foods like fruits, sherbet, sugar, rice, and coffee. Merchants from Genoa and Venice settle in Crete and Cyprus where they brought goods from Muslim merchants and sold these goods in Europe. European began to take an interest in Asia as they began to come across silk and spices from Asia, which they considered as a luxury.              

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
