Because credit cards earn at different rates in different countries, the conversion rates are also different. You've gotten info from a number of countries above, but to get the best info for your specific product, you need to either look at the chart posted by tedhl or call your bank directly. If you've already tried your bank in Dubai (which one?) then it is possible that they are not linked with Asia Miles in the program, since partners are different in different regions. In that case your best bet would be to move your points to another oneworld partner (Royal Jordanian for instance?) as this would give you the best chance to redeem on CX flights by using those points.
