US-China space race heats up despite decades-old collaboration ban

Space cooperation between the US and China remains restricted despite growing opportunities. A long-standing congressional ban, known as the Wolf Amendment, blocks most civil collaborations between the two nations. Yet, recent exchanges—like NASA's access to China's lunar samples—show signs of cautious engagement in an otherwise tense relationship.

The stakes are high as both countries push ahead with ambitious moon programmes, backed by rapid advancements and heavy investment in space technology. The Wolf Amendment was introduced in 2011 by Congressman Frank Wolf to address human rights concerns in China and prevent technology leaks. It bars NASA, the National Space Council, and the White House's science office from working with Chinese entities without explicit approval from Congress. Despite this, NASA obtained lunar soil samples from China's Chang'e-5 mission in late 2023, marking a rare exception under the restrictions.

China's space capabilities have expanded dramatically over the past decade. Successful orbital launches climbed from 19 in 2015 to 66 in 2024. Investment in its commercial space sector also surged, exceeding 15 billion yuan in 2024 alone. Alongside Russia, China is developing the International Lunar Research Station, a direct counterpart to the US-led Artemis programme, which now includes 55 signatory countries.

US officials recognise potential benefits in limited collaboration. Shared technological progress, risk reduction in joint missions, and strategic advantages against common geopolitical rivals make engagement appealing. Open communication in space can also foster predictability and trust. Yet, tensions persist, with Freedom House rating China's fundamental freedoms at just 9 out of 100 for the past four years.

The US has a history of successful international partnerships, most notably the International Space Station. But when it comes to China, the Wolf Amendment keeps cooperation tightly controlled—even as both nations race toward the moon. The Wolf Amendment continues to shape US-China space relations, allowing only narrow exceptions like the lunar sample exchange. China's rapid growth in launches and investment contrasts with US-led initiatives such as Artemis, which now involve over 50 nations. While strategic and scientific incentives for collaboration exist, legal and political barriers remain firmly in place.

For now, both countries advance their lunar ambitions separately, with limited but notable points of contact.
