The $584 Billion Relationship

The U.S.-China trade relationship has a clean three-act structure. Act One (1999–2008) was the Great Opening: China joined the WTO, American imports quadrupled from $82 billion to $340 billion, and Walmart filled its shelves with goods from Guangdong. Act Two (2009–2017) was Mature Dependency: imports stabilized around $450–$500 billion, the deficit calcified in the $300–$375 billion range, and the relationship became too large and entangled for either side to easily exit. Act Three (2018–present) is the Attempted Breakup: tariffs, export controls, the pandemic, and geopolitical confrontation have begun — slowly, unevenly — pulling the two economies apart.

In 1999, total U.S.-China goods trade was $95 billion. China was America’s fourth-largest trading partner, behind Canada, Mexico, and Japan. Two decades later, in 2018, the total had reached $662 billion and China was second only to Canada. By 2024, after six years of tariffs and trade war, the total had retreated to $584 billion — still enormous, but no longer growing. For the first time since WTO accession, the trend line has bent.

The negotiations to bring China into the WTO lasted fifteen years. When they concluded in 2001, China agreed to reduce tariffs from an average of 25% to under 10%, open its markets to foreign investment, and submit to WTO dispute resolution. In exchange, China received “most favored nation” status — meaning its exports would face the same low tariffs as goods from America’s closest allies. Before WTO accession, Congress had to vote annually to renew China’s trade access. After 2001, access was permanent.

The consequences were immediate and massive. American imports from China doubled in five years, from $103 billion in 2001 to $289 billion in 2006. Every major American retailer restructured its supply chain. Walmart, which had sourced primarily from domestic manufacturers in the 1990s, shifted to Chinese suppliers so aggressively that by 2005 an estimated 70% of its merchandise originated in China. Target, Home Depot, and Costco followed. American consumers received an enormous and largely invisible benefit: cheaper televisions, cheaper clothing, cheaper furniture, cheaper toys. A 2019 study by economists Xavier Jaravel and Erick Sager estimated that Chinese imports reduced the U.S. price level by 0.19 percentage points per year — a small number that compounded into hundreds of billions in consumer savings over the decade.

American exports to China grew too, but at a fraction of the pace. From $13 billion in 1999 to $71 billion in 2008 — a fivefold increase in absolute terms, but starting from such a low base that the export growth barely registered against the import surge. The goods deficit expanded from $69 billion to $268 billion, widening by roughly $25 billion per year. By 2008, the U.S.-China goods deficit had surpassed the entire GDP of Egypt, or Peru, or the Czech Republic. It was, by itself, the largest bilateral trade imbalance in human history.

The political reaction was slow to form. In the early 2000s, the prevailing wisdom in Washington held that trade with China would liberalize its economy and, eventually, its political system. “When China joins the WTO,” President Clinton said in 2000, “it will be agreeing to import one of democracy’s most cherished values: economic freedom.” This theory — that prosperity breeds pluralism — sustained bipartisan support for engagement through the Bush and early Obama years, even as factory towns across the Midwest hollowed out.

The 2009 recession marked a turning point. Chinese imports fell from $340 billion to $298 billion — the first annual decline — but recovered within a year and resumed their upward trajectory, reaching $539 billion by 2018. The growth rate, however, had slowed. Imports grew by 4–5% annually during 2010–2017, compared to 15–20% during the opening decade. The relationship had matured. The easy gains — shifting production of simple consumer goods from American factories to Chinese ones — were largely complete. What remained was complex manufacturing: electronics, machinery, chemicals.

During this period, the composition of Chinese exports to America shifted. In 2001, the top imports were clothing, toys, and shoes — labor-intensive products where China’s low wages provided an unbeatable advantage. By 2015, the top imports were smartphones, laptops, and telecommunications equipment — technology products assembled in China using components from Japan, South Korea, Taiwan, and the United States itself. Apple’s iPhone became the symbol of this complexity. The device was designed in Cupertino, its processor fabricated by TSMC in Taiwan, its screen manufactured by Samsung in South Korea, and its final assembly performed by Foxconn in Zhengzhou, China, where 350,000 workers operated the world’s largest iPhone factory. BEA counted the full factory-gate value of each iPhone as a Chinese import, even though China captured only an estimated $8.46 of the $237 manufacturing cost — roughly 3.6%.

American exports found their niche during this period too, but in unexpected categories. Soybeans became the largest single export to China by value, as the country’s rising middle class demanded more meat, and feeding the pigs required imported feed. American farmers — particularly in Iowa, Illinois, and Indiana — planted millions of additional soybean acres specifically for the Chinese market. By 2017, agricultural exports to China had reached $24 billion, making China the single largest customer for American farms. Industrial supplies (chemicals, plastics, scrap metals) and capital goods (semiconductors, civilian aircraft) filled out the export mix. We’ll examine what America buys and sells in detail in Episodes 2 and 3.

On March 22, 2018, President Trump signed a presidential memorandum ordering tariffs on up to $60 billion of Chinese goods, citing “unfair trade practices.” It was the opening salvo in a trade war that escalated through 2018 and 2019 in three waves: 25% tariffs on $34 billion of goods in July 2018, another $16 billion in August, and $200 billion more at 10–25% in September. China retaliated at each stage, imposing tariffs on American soybeans, pork, aircraft, and automobiles.

The impact on the trade data was dramatic — but not in the way advocates predicted. American imports from China fell from their 2018 peak of $539 billion to $450 billion in 2019 and $433 billion in 2020 (aided by COVID disruptions). The goods deficit shrank from its record $417 billion to $295 billion by 2024 — a $122 billion improvement. But American exports to China also fell, from $131 billion in 2017 to $108 billion in 2019, as Chinese retaliation hit. The soybean trade was cut in half overnight. The deficit improved not because America exported more, but because both sides traded less.

The quarterly data reveals the precise anatomy of the break. In Q4 2018 — the first full quarter with the broadest tariffs in effect — U.S. exports to China plunged to $23.8 billion, down 32% from the prior year’s Q4. Chinese retaliation had landed. Imports barely budged: $133.7 billion, down just 1% from Q4 2017. American companies were absorbing the tariff cost rather than switching suppliers. It took until 2019 for imports to decline meaningfully, and even then, much of the reduction reflected rerouting through Vietnam and Mexico rather than genuinely reduced consumption of Chinese goods — as we explored in the NAFTA series.

The most recent data point is the most dramatic. In Q2 2025 — the quarter after President Trump imposed a second round of tariffs, reportedly as high as 145% on some Chinese goods — imports collapsed to $68.7 billion. That’s a 39% drop from Q1’s $112.7 billion. Q3 stabilized at $69.1 billion. If this level holds, annualized Chinese imports would fall to approximately $275 billion — the lowest since 2009. The attempted breakup is accelerating.

The goods deficit commands the headlines, but the full U.S.-China economic relationship extends well beyond merchandise trade. Services trade tells a strikingly different story: the U.S. runs a $33 billion services surplus with China, driven overwhelmingly by travel and education. Some 370,000 Chinese students attend American universities, paying full international tuition that averages $40,000–$60,000 per year. Add living expenses, and Chinese students contribute an estimated $15–$20 billion annually to the U.S. economy — the single largest services export to any country. We’ll explore this in Episode 5.

Investment flows reveal a relationship far shallower than the trade numbers suggest. U.S. foreign direct investment into China was just $5.1 billion in 2024 — a fraction of the $38 billion invested in Canada or even the $18 billion in Mexico. Chinese FDI into the United States was even smaller at $1.8 billion. For a $584 billion trade relationship, the investment ties are remarkably thin — and getting thinner. Meanwhile, China has been aggressively selling U.S. Treasury securities, reducing its holdings by an estimated $129 billion in 2024 alone. The financial decoupling is running ahead of the trade decoupling, as Episode 8 will explore.

The current account balance — which adds services, investment income, and transfers to the goods figure — reached −$298 billion in 2024. Services offset $33 billion of the goods deficit, but primary income (investment returns) subtracted another $30 billion, because the U.S. pays more to Chinese holders of American securities than it earns from its investments in China. The full picture is worse than the goods deficit alone.
