China's economic slowdown in 2015 will have important consequences for countries in the region and beyond. For most countries, even the sub-7 percent GDP growth expected this year - and in the coming years - would be a cause for celebration. After three decades of double-digit growth, however, the weakening performance of what is now the world's second-largest economy is a significant source of concern - and not just for the Chinese.

But while China's slowdown will have negative consequences for some countries, it is also creating opportunities for others. The fate of countries in the region depends on the structure of their economies - and, crucially, how they can adapt to their giant neighbor's ongoing economic transformation.

Countries that produce raw materials, such as copper, oil and minerals, for manufacturing in China are already seeing the biggest changes. China's industrial slowdown means a corresponding reduction in world demand for these commodities. Countries such as Kazakhstan and Chile, whose economies are heavily concentrated in such sectors, are finding the contraction a serious challenge.

Countries that produce intermediate goods are also feeling the pinch. Japan, for example, manufactures parts and components that are exported to China for the production of consumer electronics. In other words, its value-added exports to the world often pass through China. As a result, China's slowdown has had a noticeable effect on Japan's export performance.

But the fate of commodity and intermediate goods exporters is not set in stone. Consumers are not buying fewer smartphones, electronic toys or computers; the production of these goods will simply move from China to lower-cost producers. Vietnam, for example, has greatly increased its production and exports of smartphones and consumer electronics - an area where China used to enjoy absolute dominance - partly by attracting more foreign direct investment.

Other countries such as India and Indonesia could in principle emerge as the new export giants. But for this to happen, these countries will have to invest heavily in infrastructure and policy reforms that make their logistics and investment climate globally competitive.

Another set of countries that have felt the impact of China's rebalancing sell products and services to Chinese consumers. Despite slower growth, China's household consumption has been rising and the country's market remains one of the world's most promising. Companies that can take advantage of higher consumer spending will do well.

Thus far, countries outside Asia - such as Germany with its auto industry and the United States with its high-tech innovation - have been the primary beneficiaries of rising incomes in China. But Asia-Pacific countries have also gained ground. Singapore and Australia are taking advantage of the rising demand for high-quality education in China by expanding exports of college services. Japan is benefiting from Chinese tourists' aggressive spending habits, so much so that the phenomenon - known as bakugai - has been termed the buzzword of the year in Japan.

A third set of countries that stand to benefit comprises those that primarily compete with China. These economies can increase their global market share as China retreats from certain sectors. Precisely because of its own success, China's labor cost has risen by more than 100 percent in the last 10 years, leaving many other countries - not just Vietnam or India, but also other populous countries like Bangladesh and Myanmar - with much lower labor costs.
