The only big/heavy brewing items I can think of would be primary fermenters (plastic buckets), a boil pot, and a glass secondary vessel. The rest is fairly light.
Find a stainless/aluminum pot capable of 2-5 gallon boils. You can get this there or probably have it if you have a restaurant.
Find a good food-grade 6-6.5 gallon bucket and lid. Get a glass bottle that can hold 5 gallon somewhere (or several 1-2g. glass bottles) that you can stopper/airlock. Food-grade buckets can be obtained for restaurants, etc. so if you own one, you are good to go. Try order some sot sauce or something in bulk...
You can do your primary fermentation in the plastic (just need one hole drilled in top for the airlock) and its ideal to do secondary/clearing in glass, but if you can't obtain glass, leaving it in plastic 2-3 weeks shouldn't hurt much.
Have your friend send you some stoppers, plastic tubing, and airlocks from the US. Also, bottle caps. Airlocks, caps, and stoppers weigh maybe 1-2oz each. He can send this with the first shipment of ingredients he sends you. Ingredients are going to weigh probably 10lb. for a "kit" of grains, malt extracts, etc. so hopefully shipping 10lb isn't an issue. Either way, the stoppers and small equipment is easier to ship than ingredients. This should be all you really need to get started.
Of course you will need bottles to bottle the 5 gallons of beer when complete. You'll need 45-50 bottles roughly, so hopefully you can get these there. I'd assume you could if you run a restaurant, but who knows... They cannot be twist top, but bottle opener type (and able to accept carbonation) capable of taking the new crowns/caps your friend will send. Or you can use plastic soda bottles if necessary. 20oz. Coke or A&W root beer will work. The root beer is better due to the brown plastic. Drink a lot of these and you'll have some fairly cheap bottles (cheaper than shipping). Or, if you are looking to do this in bulk and to serve on tap at the restaurant you will need corny kegs and C02. This is definitely heavy, so I'm not sure how you would get this. Bottling is probably a better route... Heck, you can always bottle in soda bottles and just pour into a glass for yourself and/or customers?
That should do it. I don't know much about Thailand, the products they sell (do they even sell A&W rootbeer there?!), shipping, etc. but you should be able to pull it off if the shipping of ~10lb. at a time isn't too costly...
