Without the demand from China, the decline in prices would have definitely been more serious. It is therefore ridiculous to point one's finger at China for this issue.

In addition, a large number of Chinese tourists have spent a record-breaking amount of money in foreign countries, helping to stabilize the global market. For example, 6.11 million Chinese visited South Korea in 2015, accounting for 40 percent of the total foreign visitors to the country. Chinese tourists spent $2,170 on average in South Korea, contributing $22 billion, or 2.6 percent, to the country's GDP.

China's outbound investment is also an important source of world economic growth.

According to figures from the United Nations Conference on Trade and Development, global flows of foreign direct investment (FDI) jumped 36 percent in 2015. However, developing economies saw their FDI growing only 5 percent, and most of the investment went to developing Asia, with inflows to other developing countries even declining by more than 10 percent.

Against this backdrop, China's outbound investment, especially to developing countries, has grown rapidly. In 2015 the country invested a record high of $118.02 billion abroad, up by 14.7 percent, much of which was parked in developing countries.

In 2015 Chinese companies made a number of direct investments amounting to $14.82 billion to 49 countries along the Silk Road Economic Belt and the 21st Century Maritime Silk Road, 18.2 percent higher than 2014's figure. Most of those countries are developing economies. While many developing countries are facing outflows of foreign investment, growing direct investment from China has boosted their economic growth tremendously.

While most of major world currencies are currently depreciating sharply against the U.S. dollar, the yuan hasn't depreciated as drastically, which has helped stabilize the global financial market.

In 2015, the euro and Japanese yen devalued by 16.5 percent and 12.5 percent respectively against the U.S. dollar. India, whose economic growth was faster than China, saw its rupee depreciate by 3.9 percent against the U.S. dollar. Since most other currencies are depreciating against the U.S. dollar while the yuan remains relatively stable, the takeaway is that the real effective exchange rate of the yuan is appreciating significantly. According to the Bank of International Settlements, the yuan's monthly average real effective exchange rate index rose by 9.7 percent in 2015.

Under such circumstances, even though China's exports have declined, it didn't choose to devalue its currency. Instead, China chose to assume its responsibilities as a major economic player.

It is easy to see that China has not stymied world economic growth. On the contrary, it has made significant contributions to its development and stability.
