It was proposed in the Tung Chung New Town Extension Study, to serve a proposed new 120 ha (1.2 km2; 300 acres) of reclaimed land, along with a new Tung Chung West station.[4] The proposal was approved by the government in 2023.[5]
The Tung Chung East station will be constructed at ground level, similar to Sunny Bay, to not affect the existing railway network.
As of May 2023, the plan is to have two exits on the at-grade concourse. [6]
