Taiwan’s foreign minister warned Monday that Beijing’s establishment of diplomatic relations over the weekend with Chad, one of Taiwan’s few remaining allies, would hurt relations across the Taiwan Strait.

“It’s actually a setup by the P.R.C. to humiliate Taiwan and that’s not acceptable, and it’s going to have repercussions in terms of cross-straits relations,” Mr. Huang said. [Full Text]
