Taiwan's government says more of its citizens have vanished or been detained in China, and Beijing now openly admits questioning a young Taiwanese traveler for six hours over past human rights work — bad news for anyone traveling across the strait.

• Taiwan's mainland affairs body counts 431 people who went missing, were held for questioning, or lost their freedom in China since early 2024, with five new cases in one week.
• Most of that total is people believed to be locked up by Chinese authorities, with the rest missing or stopped and questioned.
• Beijing's Taiwan Affairs Office admitted grilling a Taiwanese visitor for six hours simply because they once worked for Amnesty International's Taiwan branch, calling the group an anti-China front and the questioning lawful.
• Taipei's read: China is now punishing legal activity done inside Taiwan, aiming to scare people into censoring themselves before joining any group or event.
• Amnesty is not anti-China but anti-authoritarian, and it backed Taiwanese prisoners of conscience during the martial law era — history Beijing wants erased.

Outlook: Expect Taipei to keep publishing these weekly warnings and travel to China to look riskier for anyone with a civic or rights background.
