Taiwan's opposition KMT says letters sent by chief prosecutors to local village and borough chiefs go beyond normal anti-vote-buying advice, calling it intimidation dressed up as legal education ahead of local elections.

• Chief prosecutors across Taiwan mailed election-law warning letters to neighborhood leaders in their districts.
• The letters mention Chinese interference in elections and the Anti-Infiltration Act, which is new compared with past anti-bribery mailings.
• The KMT says previous letters stuck to vote-buying and never covered travel or contact with China.
• Lawyers at the KMT's press event say exchanges with China are legal, and the wording could scare people into thinking any trip is a crime.
• The Supreme Prosecutors Office denies political pressure and says every offense listed has a legal basis; the Justice Ministry says it respects the office's authority.

Outlook: Expect the fight over how far election-law enforcement reaches into China travel to sharpen as Taiwan's local elections approach.
