I think It is easier than that:
1-Very small market, in a very large territory.
2-Taxes too high.
3-Not Official dealer in country, just official importer (ONE official importer for all country).
4-Official importer does not care about after sales service.
Enough to remove extended warranty, doesn't It?.
Remember USA is the largest market in the whole world after China. They NEED to sale to You. Ha Ha.
