In the 1980s, the share of the US in the world econ

omy was more than 20 percent; in the past four decades, it has steadily

declined to 15 percent. At the same time, China’s share (in purchasing powe

r parity terms) has soared from 5 percent to about 20 percent. While the PPP indicators inflate the

pace of progress, the trend lines do herald a coming structural shift in the world economy.

China can foster the share of developing nations

In the future, the well-being of the advanced economies will de

pend on the rising living standards in less-wealthy nati

ons. And just as US leadership supported the role of the advanced countries in the 20th century world, Ch

ina has the potential to foster the share of emerging and developing countries in the 21st century.

In particular, the China-proposed Belt and Road Initiative can redirect domestic overcapacity and ca

pital for regional infrastructure development to improve trade and relations with Southeast and So

uth Asia, Central Asia, the Middle East and Europe-even across the Americas and Sub-Saharan Africa.
