China & the United States

$584Ba year

U.S.–China goods trade was essentially zero at normalization in 1979. By 2024 it hit a record $584 billion — even as both capitals raced to decouple.

Two economies that barely traded in 1979 are now the most entangled — and most rivalrous — on earth. The modern relationship dates to normalization in 1979, when bilateral trade was negligible; today the two are deeply entwined in goods, debt, capital, and technology even as they slide toward strategic rivalry. This traces the arc from opening to integration to decoupling — the trade balance, China's holdings of U.S. debt, the military balance, and the tech and tariff fronts — and lays out how Washington's engage and contain camps read the same facts.

The arc in one paragraph

The modern relationship runs through four phases. It opened as a Cold-War alignment against Moscow (1972–1989), matured into deep commercial integration after China joined the world trading system (1990s–2000s), tipped into strategic friction as China became a peer economy (2010s), and has since slid toward managed decoupling in trade, technology, and finance. Each phase left the two more entangled than the last — which is precisely what makes the current rivalry so hard to unwind.

Why it started

The opening was strategic before it was commercial. Nixon and Kissinger went to Beijing in 1972 to split the communist bloc — to play China against the Soviet Union. Full normalization followed in 1979, and with it the Taiwan Relations Act, which committed the U.S. to help Taiwan defend itself while recognizing Beijing. Trade was an afterthought: barely $2 billion a year, essentially a rounding error.

The commercial explosion came later — after Deng Xiaoping's reforms, after PNTR in 2000, and above all after China joined the WTO in 2001. What began as a Cold-War handshake became the deepest economic entanglement between two rival powers in modern history.

Why it turned

Washington's bet was that trade and growth would make China freer and more like the West. Instead China grew richer, more assertive, and more authoritarian. As it became the world's #2 economy (2010), launched Belt and Road, and published Made in China 2025, the U.S. consensus shifted from "engage" to "compete." The 2018 tariffs and the 2022 chip controls were the hinge — the moment the relationship's default setting flipped from integration to rivalry.
