The FBI's arrest at Los Angeles airport of a woman suspected of conducting espionage on China's behalf is a diplomatic and security warning for Taiwan, but it also shows that US-Taiwan law enforcement cooperation is working.

• The woman is alleged to have surveilled Lai Ting-yu, the son of Taiwanese President Lai Ching-te, in the United States.
• The Presidential Office called this a textbook case of transnational repression and issued its strongest condemnation.
• The targets of Beijing's pressure have expanded from politicians themselves to their family members overseas.
• Taipei publicly thanked US judicial authorities for their assistance and stressed that it would work with democratic allies to counter such activity.

Outlook: With the case now entering the US judicial process, cooperation between Taiwan and the United States against transnational repression is expected to grow closer, while China is likely to deny and push back against the allegations.
