Mario: Markets react to talk of a US-China trade war, with global attention on China-Taiwan risk. I spoke with Professor Yasheng Huang to discuss China’s real economy, what a trade war could look like in the next two to three years, and whether China might invade Taiwan.
Mario: You describe the rare-earth export restrictions China announced as a major move. China refines roughly 90% of the world’s rare earths, mines about 70%, and controls a crucial supply for tech, AI, missiles, private and fighter jets. The official rationale is that the policy is an export control rather than an export ban; those using Chinese-processed rare earths must submit applications. Civilian usage is said to be okay, defense-related usage will be scrutinized or prohibited, though the definitions of civilian versus defense usage are unclear. The move, if fully implemented, would shock global supply chains since rare earths are embedded in almost all electronic production.
Professor Huang: The policy could trigger a global production disruption because rare earths are used universally in electronics—phones, computers, and more. The threshold for needing approval is set very low, effectively implicating almost every user of Chinese-processed rare earths. The policy isn’t narrowly targeted at the US; it affects any user of the Chinese process. If fully enacted, it would be a broad economic shock.
Mario: The timing follows a series of US actions: fentanyl tariffs on China around 10%, broader US tariffs on many countries including China in April, a Geneva truce for 90 days, and then May’s halting of five-nanometer chip exports to China. August saw partial relaxation, with seven-nanometer chips allowed but capped revenues from China for NVIDIA and AMD at 15%. Then mid-September, the US imposed docking fees on Chinese ships calling US ports, and China retaliated with a rare-earth move. Why did China take this step, and does it aim to pressure for a summit with Xi Jinping and Donald Trump later this month?
Professor Huang: The broad timeline is accurate, though mid-September docking fees added asymmetry in favor of the US. The rare-earth move likely predated that, possibly prepared for a summit in South Korea. It’s not well tailored as a bargaining chip since it would affect many countries, not just the US. China may be signaling leverage ahead of a potential Xi-Trump meeting and reflecting tensions in agricultural exports—China has largely stopped buying US soybeans, causing farmer distress. The rare-earth policy is a high-pressure tactic that may overreach.
Mario: You compare China’s stance to the US, noting that China seems to be pushing back more aggressively than other countries, and that this move could accelerate a shift away from US-dollar dominance toward hard assets like gold or Bitcoin, and toward domestic rare-earth processing in many countries. Could this be a long-term strategic disadvantage for China?
Professor Huang: In the short term, China has substantial bargaining leverage in rare earths since processing capacity is scarce elsewhere. In the long run, the move is likely to spur other countries to build processing capacity, reducing China’s leverage. The analogy with Apple’s supply diversification after China’s zero-COVID policies shows such diversification will take time. If other countries build processing capacity, the relative power shift could occur over a longer horizon. The geopolitical calculus should consider timing: short-term gains may come at long-term costs.
Mario: You discuss the difference between hard assets and soft assets like the dollar, and whether China’s move could motivate countries to diversify away from rare earth dependence. Could you expand on that?
Professor Huang: Hard assets (gold) and soft assets (dollar credibility) differ in impact. Rare earth processing capacity is a hard asset-like dependency; diversifying away from China’s processing could reduce China’s leverage over time. However, short-term disruption is likely to be broad, since electronics’ reliance on rare earths is pervasive. In the long run, countries will build refining and processing capacity, making the West less dependent on China for these inputs.
Mario: Turning to China’s economy, some critics warned of collapse in the early 2000s, but China grew. Now, growth is around 5%, though debt-to-GDP has risen and productivity appears to be slowing. How does Professor Huang reconcile these views?
Professor Huang: The early-2000s collapse predictions were incorrect, but today China faces real strains. The debt-to-GDP ratio has risen since 2008, raising the incremental capital needed to generate each percentage point of growth. Productivity has trended downward; there is a difference between the business-executive view and the academic view. Executives see impressive factories and automation, while academics point to waste and overbuilding—factories producing goods no one wants, empty housing, and higher logistical costs. Net economy-wide productivity is negative, due to inefficiencies offsetting gains.
Mario: You compare democracy and autocracy. Some argue China’s centralized, long-term planning works for growth, but Professor Huang notes that personal income growth in China was highest when the system was less autocratic. He argues Deng Xiaoping’s openness—less autocratic than today—drove significant growth, while Xi Jinping’s more autocratic leadership coincides with a growth slowdown. How does he view the balance between political structure and economic outcomes?
Professor Huang: He distinguishes between ideal democracy and current practice, arguing the US system is flawed in ways that impede governance (gun control, healthcare, etc.). He notes that autocracy is not the sole cause of growth; historically, less autocratic or more open autocracies in East Asia grew more rapidly than more autocratic regimes. For China, the data suggest that more open regions grew faster than tightly controlled ones. The correlation does not support the idea that autocracy automatically delivers robust growth.
Mario: Finally, you discuss Trump’s China policy. Trump’s transactional approach, allied with a perceived US weakness, has shifted dynamics. How will China respond if Europe leans toward China, and could Ukraine policy influence that?
Professor Huang: Trump elevated autocracy’s legitimacy, potentially aiding leaders like Xi. Europe might move closer to China if China softens its Ukraine stance; however, the rare-earth move complicates that. Indian leaders understand Trump’s transactional approach, encouraging engagement to safeguard national interests. The global balance will depend on China’s actions and Europe’s response, with the Ukraine position remaining a critical factor.
