Last year Pakistan exported goods worth 21 Billion. Bangladesh exports were close to 35 Billion.
Your ideas are stuck at concepts about Bangladesh from fifteen years ago like a lot of Indians here. Bangladesh industrial output contains a lot more than chaddis and t-shirts. In fact Pakistan is a more traditional exporter of t-shirts/undershirts than Bangladesh is. Enough high quality textile investments were made locally - that we have diversified (even textile exports) well beyond those simple items with very low margins.
The recent impetus into mens'/womens' tailored fashion, denims (Bangladesh is the 2nd largest denim exporter worldwide and a pioneer in green production). and home textiles are just some other textile export areas.
Bangladesh produces most of the home electronics, small electrics and kitchenware consumed locally, as well as pharma, ceramics, seafood which are export-growth sectors. Industrial export variety is comparable to Pakistan, if not better. Here's a list (though not comprehensive) of non-textile exports. This list does not include niche items produced in export zones which are varied and numerous.
- Electronics apparatus (including computers, cellphones, smart TVs)
- Electrical machinery (including power electronics equipment)
- Vehicles (mostly two wheeler motorcycles, buses, trucks, as needed for domestic consumption)
- Rubber, rubber articles (such as vulcanized tires etc.)
- Plastics, plastic articles (housewares and various cookware implements)
- Meat/seafood preparations (shrimp exports mostly)
- Cereals (rice, pulses)
- Shipbuilding (we made some small vessels for Karachi port but we can build OPV's and frigates for you too if needed)
- Bicycle (and parts) exports
- Steel products such as long items (rebar) and processed items (metal housing, some of which is being exported to Pakistan).
- Jute and jute goods
- leather items (shoes belts etc.)
Future growth investment areas include Motor vehicles, Gems, precious metals processing, Mineral fuels processing, Optical (and technical, medical) apparatus etc. some of which is already in the upswing.
