Taiwan will not be a part of the Indo-Pacific Economic Framework when the U.S. administration of President Joe Biden launches it this week as a key tool for regional engagement, White House national security adviser Jake Sullivan said Sunday.

Whether Taiwan will become a member of the IPEF initiative has been drawing attention as the move would likely upset China, which views the island as its own. The framework will be launched on Monday.

Still, Sullivan said the United States is looking to deepen its economic partnership with Taiwan, including on high-tech issues.

"We are looking to deepen our economic partnership with Taiwan including on high technology issues, including on semiconductors and supply chains," he said.
