Chinese Ghosts
To the Editor:
G. John Ikenberry propagates a misconception ("The Rise of China and the Future of the West," January/February 2008) by using GDP at purchasing power parity (PPP) to conclude that China will surpass the United States in terms of economic weight sometime around 2020. A nation's weight in the world economy is primarily exerted through imports and exports, investment and capital flows. All of these take place at currency exchange rates, not at PPP. A haircut in Wuhan may cost a dollar's worth of yuan and be worth $15 to the Chinese GDP at PPP, but its effect on the outside world's economy is nothing, at least not until China can export haircuts.
Per capita GDP at PPP is a good measure of affluence, that is, of the individual standard of living. But the appropriate measure of the potential influence of a national economy on the rest of the world is the national GDP at exchange rates. China plays a major and growing role in the global economy. But even if its remarkably high growth rate does not falter, a continued six percent gap between the United States' and China's GDP growth would still leave the Chinese economy in 2020 at about one-third the size of the U.S. economy.

No, it is not a silly question -- merely one that is not asked often enough. Odd as it may seem, the country that is home to a fifth of humankind is consistently overrated as an economy, a world power, and a source of ideas. Economically, China is a relatively unimportant small market; militarily, it is less a global rival like the Soviet Union than a regional menace like Iraq; and politically, its influence is puny. The Middle Kingdom is a middle power. China matters far less than it and most of the West think, and it is high time the West began treating it as such.
Communist China's drive for major power status-an urge to narrow the gap between herself and the two superpowers-has been the central objective of her campaign for economic development. In pursuit of this goal, Chinese planners have concentrated on expanding as rapidly as possible the country's capacity to produce capital goods and military matériel. For this purpose, a mechanism for institutionalizing a high rate of involuntary saving and for channeling it into the desired lines of investment had to be fashioned.
China has achieved stunning economic progress since the 1970s, thanks to aggressive liberalization, a commitment to exporting high-tech goods, and a massive injection of foreign investment. Although this unprecedented success is understandably unnerving to China's neighbors and trading partners, it should not be cause for worry; China, the United States, and the rest of the world still have lots of business to do.
