Beijing–Hong Kong (Taipei) corridor
The Beijing–Hong Kong (Taipei) corridor is a proposed high-speed railway corridor in China and Taiwan. It is planned to run in a north–south direction from Beijing to Hong Kong, with a branch leading from Hefei to Taipei across the Taiwan Strait, of which the Taiwan section is proposed unilaterally.
