In this video, Motley Fool Analyst Blake Bos tells us how Coca-Cola (NYSE:KO) and PepsiCo (NYSE:PEP) are doing battle in various ways in some of the world's emerging markets. We hear how Pepsi's cost-effective approach at challenging the already well-established Coke in China may or may not pay off big, and how, after 60 years of America's companies being unable to do business in Myanmar (also known as Burma), Coke is entering the Burmese market, with Pepsi hot on its heels. Finally, we hear about another little soda company from Israel that takes a very different approach and may be a disrupter for the big guys.
