How dependent is America's arsenal on China's critical mineral supply?
critical minerals for its advanced weapon systems, but it has relied on China for most of those inputs.
As Beijing tightens export restrictions, there is a growing risk to the
Pentagon's military readiness and supply chain security.
The big picture
China dominates the global supply of
rare earths , including controlling more than 90 per cent of the world's processing and refining. It also has an edge in most other critical minerals, such as refined gallium, of which it controls 98.8 per cent of the output.

A closer look
In recent years, Beijing has leveraged its dominance in critical mineral production and refining as a key negotiating point in trade wars, as well as targeting defence industries in the US and its allies.
In July 2023, Beijing imposed controls requiring exporters to seek permission to ship eight gallium-related and six germanium-related products abroad. The list was expanded to include antimony in August 2024.
In December, the Chinese commerce ministry imposed export bans on gallium, germanium and antimony to the US, which affects American military end users.
In April, Beijing imposed trade restrictions requiring a special export licence for seven categories of medium and heavy rare earth elements (REE) – samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium – as well as magnets and other finished products that contain them to be shipped out of China.

Competition should be about innovation and quality, not the price
As Beijing works aggressively to make sure the economy meets the 5 per cent growth target at year end, one new tool in its arsenal is to amend a key law to discourage vicious price wars that have plagued multiple sectors in recent years. From food delivery and e-commerce to solar power and electric cars, steep price cuts – with the aim to drive out competitors but which also undercut one's own profits – are fuelling deflationary pressure. That has led regulators to propose urgent amendments to an old pricing law. A public consultation is open until August 23. With transparency and an open mind, the authorities can use positive public feedback to fine-tune the changes. In the existing law, firms are banned from selling goods below cost to eliminate competitors or monopolise the market. The new amendment adds the condition that businesses cannot fight each other by dumping products at below-cost prices. With more transparent price regulation and oversight, they will also be prohibited from 'leveraging data, algorithms and technological tools' to chase clients and beat rivals. So far, market reactions have been positive. Listed companies in consumer services, non-ferrous metals and financial companies – sectors that have experienced cutthroat competition or what officials have termed 'involution' – have seen share prices move up since the news broke. There is, of course, a counterargument that market forces alone should decide prices. But in such cases of market failure, supervision and regulatory intervention are called for. Companies ought to compete on quality and innovation rather than price. A proper legal framework will work better to guide businesses and promote healthy competition, rather than for authorities to deliver ad hoc admonitions to offending firms when the situation has already become dire. In early July, the Ministry of Industry and Information Technology warned 14 major solar firms against a vicious price war and overcapacity. The share prices of some of them rose on the news, as markets expected price cutting eating into profits would stop. But such intervention is unsystematic. A transparent legal framework should be business-friendly with clear rules and regulations. Moderating or even eliminating involution will allow more time for companies to phase out outdated practices to better compete.

Will Chinese Z-10ME attack helicopters now power Pakistan air force?
Images circulating online suggest Pakistan's military has received a shipment of Chinese-made advanced attack helicopters, a version of which has been deployed by the People's Liberation Army (PLA) near China's mountainous border with India In the past week, photos and videos of the Z-10ME , the export version of the Chinese multirole attack helicopter, have appeared on Pakistani social media accounts. On Tuesday, a social media user believed to be an active-duty member of the Pakistan Army uploaded a video clearly showing the helicopter airborne, apparently conducting field airport support missions from a military base. The video was captioned: 'First look at Pakistan's Z-10ME attack helicopter armed with next-gen air-to-ground missiles.' This followed a photo posted on Monday by another user showing a Z-10ME undergoing ground maintenance. The helicopter bore the words 'Pakistan Army' and serial number '786-301' on its fuselage and tail. The image marked the first credible evidence of the Z-10ME's operational status within the Pakistan Army Aviation Corps.

China's central bank vows to boost money supply, cut borrowing costs in growth push
China's central bank has pledged more liquidity and lower borrowing costs in the second half of the year, as part of a broader strategy to boost growth and implement long-term financial reforms. At a key mid-year meeting on Friday, the People's Bank of China said it would maintain a moderately loose monetary policy by cutting reserve requirement ratios and key interest rates, while making full use of targeted tools to lower overall financing costs. Amid external uncertainties, sluggish domestic demand , as well as persistent deflationary pressure, the central bank also vowed to refine its monetary policy framework, guide market expectations more effectively, and strengthen coordination with fiscal policies to support innovation, consumption, small and micro businesses, and exports. In particular, the bank said it would target 'idle capital circulation and ' involution style ' competition in the financial industry', a reference to self-defeating competition that drains resources without improving outcomes. This kind of competition has been a key concern for policymakers in various parts of the economy. However, Xu Tianchen, senior China economist at the Economist Intelligence Unit, said that a new round of rate cuts or reserve requirement ratio reductions was unlikely in the third quarter.
