The programme, broadcast on World Consumer Rights Day by state-run China Central Television (CCTV), annually takes aim at alleged unethical behaviour by makers of well-known products and this time accused Nike of misleading advertising, AFP reports.
Nike had claimed that one of its basketball shoes had air-cushion insoles when it did not, the broadcaster said.
Bloomberg News quoted a statement issued by Nike as saying the company was "committed to providing consumers with the highest product quality and service, and we will fully cooperate with the government regulators regarding their enquiries".
It is not the first time the programme has launched such an attack, forcing a globally-recognised brand to launch damage-control measures to protect its position in China's huge and coveted consumer market.
Apple was accused by the show in 2013 of dishonesty in its customer service and returns policies, prompting an apology from CEO Tim Cook.
The programme's past targets also have included fast-food giant McDonald's, Jaguar Land Rover Automotive, Volkswagen and Mercedes-Benz.
Wednesday's programme also took aim at Japanese retailer Muji, saying labelling on some of its food products had misrepresented that they originated in areas of Japan hit by the 2011 nuclear power plant disaster. Such products are banned in China. ■
