The Formosa Club — a coalition of Taiwan friendship groups — on Tuesday congratulated Vice President William Lai (賴清德) on his victory in Saturday’s presidential election and voiced concern over apparent Chinese involvement in Nauru severing diplomatic ties with Taiwan.

Nauru switched recognition to China two days after Taiwan’s presidential and legislative elections, which the Formosa Club said in a statement was based on Beijing’s claim that Taiwan is part of China, a misinterpretation of UN Resolution 2758.

The incident “highlights the fact that China has utilized the distorted interpretation of this resolution to isolate Taiwan internationally,” wrote 25 cochairs of the club, which comprises cross-party European and Canadian legislators.
