Economic cake must be shared in a fairer way

Editor's note: Many domestic problems of major economies have exerted influence on international issues, said Zheng Yongnian, a researcher in East Asia studies with the National University of Singapore, in a recent interview with Xiakedao, a WeChat account run by People's Daily. The following are excerpts of his responses to questions on the risk prevention and control in domestic and international politics:

In his speech at the World Economic Forum in Davos, Switzerland, last week, Vice-President Wang Qishan called on countries to work together to make the global economic cake bigger instead of focusing on how to divide it.

Although the United States enjoys the lion's share of the global cake, it has not divided this fairly at home. But it will not solve its own problems by waging trade wars with other countries, which will only externalize its internal problems, making the situation even more complicated.
