Plans unveiled for building all 2022 Olympic venues

All newly built competition-related venues in Beijing's two zones are scheduled to be finished by June 2020, while transformation of eight existing venues from the 2008 Summer Olympics to serve competition, ceremony and media functions in 2022 will be completed in 2021, according to the office.

"We are entering into the full construction phase from the general planning stage this year as we speed up building to push the major projects to take shape on schedule," said Ding Jianming, deputy director of the office.

"The release of the general plan and deadline will provide us with a measuring stick to break down the projects, accelerate the progress and deliver on time."

This year's priorities－the main concrete and steel structures of the speed skating oval and a new short-track speed skating training center in the northwestern downtown area－will be finished by year's end, officials said.
