Xi Jinping, China's president, may have deliberately revealed how he plans to strike back at the US in the trade war by taking a trip to a magnet factory in the east of the country Monday.

Xi on Monday visited the factory of JL MAG Rare-Earth in Ganzhou city, eastern China, where he learned about the "production process and operation" of the company, "as well as the development of the rare earth industry," the state-run Xinhua news agency reported . JL MAG Rare-Earth specializes in magnetic rare earth elements.

He was accompanied by Vice Premier Liu He, the country's top economics adviser who has been leading trade negotiations with his US counterparts, Trade Representative Robert Lighthizer and Treasury Secretary Steve Mnuchin.

Xi's highly-publicized attention on the country's rare earths suggests that he could use the product to cripple the US tech and military industries, and make President Donald Trump's administration back down in their yearlong trade war .

Rare earth materials consist of 17 elements on the periodic table, which can be found in products critical to the US's manufacturing, tech, and defense industries.

The minerals are found in products from batteries and flame retardants to smartphones, electric cars, and fighter jets, according to Reuters and the Financial Times . They are used in tiny amounts, but can be crucial to the manufacturing process.

"It's signalling they know it's not only important to US high-tech industries electric vehicles, wind but also defence. That's the message they're trying to get out," Ryan Castilloux, managing director of Adamas Intelligence, a rare earths consultancy told the Financial Times.

What rare earths mean to China and the US

China is the world's largest supplier of rare earth materials accounting for 90% of global production and the US relies on it for 80% of its rare earth imports, the South China Morning Post and Bloomberg reported.

China's state-run Global Times tabloid described Xi's Monday visit as the leader's "huge support to the critical industry that has been widely viewed as a form of leverage for China in the trade war with the US, but one that also faces issues that need to be addressed."

The Trump administration chose not to impose tariffs on Chinese imports of rare earth materials in its latest tariff lists, showing its reliance on China for the materials.

The US raised tariffs to 25% from 10% on $200 billion worth of Chinese goods on May 10, and drew up a prospective tariff list on another $300 billion worth of goods days later.

China also said earlier this month that it would raise duties on $60 billion worth of American goods starting June 1, resulting in duties of 5% to 25%.

There is also "growing speculation" that China could ban the export of rare earths to retaliate against the US, the South China Morning Post reported .

Stocks in companies working with rare earth elements skyrocketed after Xi's visit, with the rally continuing into end of trading on Tuesday.

China has weaponized its exports of rare earths in the past. In 2010, Beijing cut off rare earth exports to Japan amid a maritime dispute that saw a Chinese boat captain captured by Japanese authorities.

The export ban was so powerful that Japan immediately released the captain in what The New York Times described at the time as "a concession that appeared to mark a humiliating retreat in a Pacific test of wills."

In 2011, the House Committee on Foreign Affairs voiced concerns over China's ability to use rare earth exports in its foreign policy, in a hearing titled : "China's monopoly on rare earths: Implications for US foreign and security policy."
