Uganda has given back four Taiwanese passports it held at its main airport, a small win for Taiwan but a fresh sign of how hard China is squeezing it abroad.

• Ugandan immigration officers at Kampala's Entebbe airport seized passports from Taiwanese travellers and told them to use Chinese passports for their entry stamps.
• Officials called it enforcement of Uganda's "one China" policy; one earlier traveller was sent home.
• Taiwan's foreign ministry worked through its Somaliland office and local Taiwanese business groups to get all four passports returned.
• Taipei restated that Taiwan and China do not answer to each other, and called the episode proof of Beijing's pressure tactics.
• Taiwan is urging other governments to keep politics out of border checks and accept its passports as valid travel papers.

Outlook: Expect more of these border incidents as China presses African and other partner states to downgrade Taiwan's documents.
