a high-speed rail

Mexico has annulled a deal with a Chinese-led consortium over its first high-speed railway project due to public concerns about the bidding process, the Ministry of Communications and Transport said Thursday.
The government will hold a new auction for the multi-billion-U.S.-dollar project linking Mexico City with the industrial hub of Queretaro, so as to give more train manufacturers time to make proposals, the ministry said in a statement.
Earlier this week, a consortium comprising China Railway Construction Corporation and several Mexican construction firms won the bid.
The bidding was legitimate, the statement said, adding that President Enrique Pena Nieto's decision to scrap the deal was aimed at expelling any public doubts on the project.
