The High Speed 2 rail line will be built in two phases and will serve four cities: London, Birmingham, Leeds and Manchester.

Construction of phase 1 between London and Birmingham was approved in January 2012. Construction is due to begin in 2017 with an anticipated opening date of 2026. In January 2013, the preliminary phase 2 route was announced with a planned completion date of 2032.

The UK Department for Transport estimated the cost at 43 billion pounds.

In a joint statement during Premier Li Keqiang's visit to the UK in June, the two governments said that "both sides agree to promote substantive cooperation …on rail, including high-speed rail in areas including design, engineering, construction, supply operation and maintenance on projects in China and the UK."
