WASHINGTON (AP) — President Donald Trump and Australian Prime Minister Anthony Albanese earlier this week signed a critical-minerals deal at the White House as the United States eyes the continent’s rich rare-earth resources at a time when China is imposing tougher rules on exporting its own critical minerals abroad.

The two leaders described the agreement as an $8.5 billion deal between the allies. Trump said it had been negotiated over several months.

“In about a year from now we’ll have so much critical mineral and rare earth that you won’t know what to do with them,” said Trump. “They’ll be worth $2.”

Albanese added that the agreement takes the U.S.-Australia relationship “to the next level.”

Earlier this month, Beijing announced that it will require foreign companies to receive approval from the Chinese government to export magnets containing even trace amounts of rare-earth materials that originated from China or were produced with Chinese technology.

The Trump administration says this gives China broad power over the global economy by controlling the tech supply chain.

“Australia is really, really going to be helpful in the effort to take the global economy and make it less risky, less exposed to the kind of rare earth extortion that we’re seeing from the Chinese,” said Kevin Hassett, the director of the White House’s National Economic Council.

Hassett noted that Australia has one of the best mining economies in the world, while praising its refiners and its abundance of rare earth resources.

Among the Australian officials accompanying Albanese were ministers overseeing resources and industry and science. Australia has dozens of critical minerals sought by the U.S. because they are needed in everything from fighter jets and electric vehicles to laptops and phones.

The agreement could have an immediate impact on rare earth supplies in the United States if American companies can secure some of what Australian mines are already producing, although it will take years — if not decades — to develop enough of a supply of rare earths outside of China to reduce its dominance.

Pini Althaus, who founded USA Rare Earth back in 2019 and is now working to develop new mines in Kazakhstan and Uzbekistan as CEO of Cove Capital, said it will be crucial that the contracts to buy materials from Australian mines include price floors, similar to what the American government promised MP Materials this summer, to protect against China manipulating prices.

For decades, China has used the tactic of dumping excess critical minerals onto the market to drive prices down to force mining companies in the rest of the world out of business to eliminate any competition.

“I think taking away that arrow in the quiver of China to manipulate pricing is an absolute crucial first step in Australia and the West being able to develop critical minerals projects to meet our supply chain demands,” said Althaus, who has spent nearly a quarter-century in the mining business.

The agreement underscores how the U.S. is using its global allies to counter China, especially as it weaponizes its traditional dominance in rare earth materials.

Top Trump officials have used the tactics from Beijing as a rallying cry for the U.S. and its allies to work together to try to minimize China’s influence.

“China is a command-and-control economy, and we and our allies will neither be commanded nor controlled,” Treasury Secretary Scott Bessent said last week. “They are a state economy and we are not going to let a group of bureaucrats in Beijing try to manage the global supply chains.”

The level of investment outlined in the agreement shows how serious the two nations are about addressing the problem.

“The U.S. and Australia will invest over $3 billion in joint critical minerals projects within six months. That’s a somewhat unprecedented speed of capital injection,” said Gracelin Baskaran, director of the Critical Minerals Security Program at the Center for Strategic and International Studies in Washington.

Althaus cautioned that Australia can’t supply everything the United States needs, however, so it is crucial that the U.S. continues to invest in the long-term effort to develop other mining and processing projects both at home and in friendly nations.

He said central Asia might be one of the most promising places to invest because the region has significant rare earth reserves, and the Soviet Union already did some of the initial development work when it controlled that territory.

That could cut years off the time it will take to build a new mine there.

“Keep in mind, China has almost a 40-year head start on us,” Althaus said. “We have at least a couple of decades to catch up to China in terms of being able to meet our own supply chain requirements.”
