This task is about desk research. You have to find information on Thailand on the above areas. It is important to o that because the company Coca-Cola does not know how Thailand is different. So for the product introduction and the communication campaign you have to find out what is important to know. For example, what is the population of Thailand? In which areas do the people of your target audience live (if you want to reach young professionals, I am sure that they live in cities and not in the country side – so identify the areas where they live). Also, it is important to know if there are any legal restrictions in Thailand when it comes to advertising products. For example, in Germany you have to put calories on the product packaging so that consumers can see how much the product contains. In France for example companies of alcohol have to put a sign on the bottle that pregnant woman should not drink the product.
Overall you need to identify things that impact your promotional (advertising and communication) decisions. Please focus on that
