Japan Invests $36 Billion in US Energy and Critical Minerals Amid China Tensions

Japan has unveiled plans for approximately $36 billion in investments across US oil, gas, and critical mineral projects, marking the initial phase of a broader agreement with the United States. The announcement, made jointly by US President Donald Trump and Japanese Prime Minister Sanae Takaichi, centers around three key projects designed to bolster economic ties and enhance strategic security.

Key Projects Announced

• Portsmouth, Ohio Power Plant: A large-scale natural gas-fired power plant in Portsmouth, Ohio, touted by the Trump administration as the largest of its kind in US history.
• Texas Crude Oil Export Facility: Investment in a deepwater crude oil export facility located off the coast of Texas.
• Georgia Industrial Diamond Manufacturing Site: A $600 million project to establish a synthetic industrial diamond manufacturing site in Georgia.

Strategic Context and Rising Tensions

The investments come as a diplomatic dispute between Japan and China over Taiwan continues to escalate, creating economic pressures on Japan. Prime Minister Takaichi expressed hope that these investments would strengthen both Japanese and US economic security, though she did not directly reference China .

President Trump highlighted the role of tariffs in facilitating these large-scale projects, stating, “The scale of these projects are so large, and could not be done without one very special word, tariffs.” This strategy, however, has raised concerns among US economists about potentially exacerbating inflation.

Broader Investment Commitment and US Domestic Production

These initial projects represent the first tranche of a $550 billion investment commitment Japan made to the US last year. In exchange, the Trump administration agreed to reduce US tariffs on Japanese exports, including automobiles.

The industrial diamond manufacturing project in Georgia aims to eliminate US dependence on foreign sources for synthetic diamond grit, a crucial material for advanced manufacturing and semiconductors. As Commerce Secretary Howard Lutnick stated, “We will no longer rely on foreign supply for this essential material.”

China’s Dominance in Critical Minerals and Recent Restrictions

China currently holds significant control over the critical minerals market, dominating the mining and processing of rare earths essential for various industries. Beijing has previously imposed restrictions on global imports of these rare earths, leading to economic tensions with Washington. While a deal between Trump and Chinese President Xi Jinping in October 2025 temporarily eased these tensions, US officials continue to emphasize the need to reduce reliance on China for critical minerals.

Recent months have seen China initiate restricting some rare earth exports to Japan, coinciding with a dispute between Tokyo and Beijing over Taiwan. Prime Minister Takaichi’s comments in November 2025 suggesting potential Japanese military involvement in the event of a Chinese invasion of Taiwan angered Chinese officials.

Japan’s Export Growth

Japan reported a nearly 17% increase in exports in January, partially driven by a surge in exports to China despite ongoing tensions.
