The United States’ relationship with Taiwan has “never been stronger,” Washington’s top diplomat in Taipei said on Monday, highlighting growing cooperation between the two sides in technology and advanced manufacturing.
Although the United States does not maintain formal diplomatic relations with Taiwan, it remains the island’s most important international supporter and a major supplier of military equipment.
Raymond Greene, the de facto US ambassador to Taipei, made the remarks at an event held ahead of this week’s SEMICON semiconductor trade show in Taiwan. Senior executives from major technology companies, including Microsoft and Google, are expected to attend the event.
“Our ties with Taiwan have never been stronger, especially as our cooperation deepens across high-tech and advanced manufacturing sectors,” Greene said.
He also praised Taiwan’s growing investment in the United States, describing the trend as an important part of efforts to strengthen American manufacturing.
Taiwanese companies have committed billions of dollars to investments in the US. Among the largest is Taiwan Semiconductor Manufacturing Company (TSMC), which has pledged about $265 billion for investments in Arizona.
“Taiwan is helping to re-industrialise America, starting with investments in Arizona and Texas,” Greene said, adding that US companies are also expanding their technology partnerships by establishing operations in Taiwan’s major technology hubs, including Hsinchu and Taipei.
The comments come despite occasional criticism from US President Donald Trump, who has accused Taiwan of taking semiconductor business away from the United States. Taiwan’s government has rejected the criticism as unfair while continuing to encourage its companies to increase investment in the US.
Also speaking at the event, Bill Frauenhofer, an executive director at the US Commerce Department overseeing semiconductor investment and innovation, said the US government’s semiconductor manufacturing programme was helping strengthen the country’s economic future.
He said the administration was focused not only on bringing semiconductor production back to the United States but also on creating jobs and expanding career opportunities for American workers.
The growing US-Taiwan technology partnership is particularly significant because Taiwan plays a central role in the global semiconductor industry, while Washington is seeking to expand domestic chip production and reduce dependence on overseas supply chains.
