Wynn Resorts CEO Steve Wynn was spending two hours each day on Chinese lessons back in 2006, even though Mr. Wynn is of retirement age and already worth a couple of billion dollars. But at the time, the Wynn Macau -- Mr. Wynn's latest megacasino -- was just getting set to open just off the coast of China. That's right on the doorstep of some 3 billion potential customers.

Big bets for big paydays?
In hindsight, perhaps that looks like a waste of time. After all, the business climate in Macau has since suffered from a slowing global economy and visa restrictions imposed by mainland China. Yet Mr. Wynn's next project in Macau -- the Encore -- remains on track to open in 2010. And competitor Melco Crown is quite happy to be opening its City of Dreams resort early in 2009, as rumors now abound about the Chinese government lifting those aforementioned visa restrictions.

In fact, while there will be near-term difficulties, Macau's proximity to China, and the economic growth that continues on that side of the world, lead both of these companies to expect that Macau will be a very good long-term bet.

At Motley Fool Global Gains, we agree.

We're not the only ones
There are hundreds of companies -- many of them American icons -- that continue to believe that the greatest growth over the next decade will come from the emerging markets of Asia and Latin America. Take Coca-Cola (NYSE:KO), for example. It's signed up Houston Rockets star Yao Ming to endorse its drinks in China and recently bid $2.5 billion to acquire China’s Huiyuan Juice Group. And don't forget Yum! Brands (NYSE:YUM), which is expending significant capital to start East Dawning, the firm's attempt to set up China’s first nationwide Chinese fast-food chain.

These companies and many more, including Dell (NASDAQ:DELL) and eBay (NASDAQ:EBAY), all have clear emerging-market strategies that they've executed through brand-building and acquisition. Dell, for example, has established relationships with China’s top electronics retailers, including Suning, Gome, and Hontu. eBay remains the largest investor in Latin America's top e-commerce site, MercadoLibre.

Even GE (NYSE:GE), which recently cut its dividend to conserve capital, just set up another joint venture in China.

The question we have to ask
It's clear that each one of these great American companies has a clear emerging-markets strategy. The question is -- and you had to know I was coming around to this -- do you?

We think every investor needs to have intelligent exposure to China, Latin America, and the rest of the emerging world. If you just realized you don't and you're looking to do just that, feel free to check out our Global Gains international investing service.
