China-made security equipment has been installed in Maracana Stadium, where the opening ceremony of the Rio 2016 Olympics will be held, according to the manufacturer concerned.

More than 200 security-check machines made by Beijing-based Nuctech Company Ltd will be used during this month's Olympics, which will see more than 500,000 tourists and 10,000 athletes from around the world converge in Brazil.

Chen Yongjian, general manager of the Brazilian branch of Nuctech, said the equipment will be installed in all the four major venues. Some 145 machines will be used at Maracana and 55 at Deodoro. Some machines will be also used during the Paralympic Games to be held in September in Rio de Janeiro.
