Go to a business consulting firm like IBM, Accenture etc.
Here is why: resources in the far east are tightly controlled by very few people with a lot of power. You can't even talk to a Chinese manufacturer unless you do it through a Hong Kong trading co. You're just not going to get anywhere near the points of origin. It is no biggie, no one does, without serious clout. Why do you think AIG spends so much money in China?
The markup starts there in Hong Kong.
So you have a few options: Work for an ocean shipper: Maersk, APL, Hanjin, whoever. The issues here is that most of these are not US based so you'll quickly hit a ceiling. Secondly, these businesses are not really very modern - they are sort of an old guard that is hard to displace. (Feel like leasing a few thousand - foot ships? me neither). You won't learn how the biz works.
Your other option is marine insurance. Underwriters for marine insurers make a ton of money if they are good, but the majority of that market is UK or Japanese. Insurance is a great place to be to learn about a biz because you have to assess it to death to price risk.
The problem is marine insurance is also tightly controlled by players like Marsh, WK Webster, and a few others. And because some of themhave such a history, their relationships have ossified - it is hard to break in.
That leaves consultants.
These marine insurance guys are technical dinosaurs. They have their historical relationships, there are few open standards, and this whole area of supply chain management is nonexistent. This is where insurers get ass-rammed. They (insurers) have to price risk without knowing what the fuck they are insuring. Marine insurers get crushed all the time.
Well, the insurers are bringing in consultants, who are finding out what the fuck is wrong. As is usual, consultants have fund the problem and are building a non-solution to it.
Eventually, someone is going to get it right and will keep a piece of billions in annual revenue. It could be you.
As far as selling asian products to retailers - any retailer who buys in high volumes has their own sourcing department that has Asian contacts already.
So there you go. Learn about risk.
