Cardiff manager Malky Mackay and forward Craig Bellamy were among a party of club representatives who were due to conduct promotional activities in Kuala Lumpur from Thursday.
Last month Reuters exclusively reported that Malaysian billionaire owner Vincent Tan was exploring an IPO of the team after they sealed promotion to the lucrative English Premier League.
"A schedule of events had been put in place ahead of the opening Premier League fixtures, further raising awareness of Cardiff City Football Club in Malaysia," Tan said in a statement on the Welsh club's website on Tuesday.
"However due to the current poor air quality in Kuala Lumpur, it has been decided for the welfare of all concerned to delay the trip, re-establishing plans in the future when the manager and players can better interact with Malaysian based supporters in a suitable environment."
Kuala Lumpur remained shrouded in haze on Wednesday as the environmental crisis continued after a week of thick 'hazardous' smog covered Malaysia and neighbours Singapore.
Air quality in Singapore has improved significantly in recent days but the crisis - caused mostly from fires set on palm oil plantations on Indonesia's Sumatra island - could cost the two countries an estimated $9 billion.
"It is unhealthy, especially, for athletes, who train intensively. Prolonged exposure could cause cell mutations leading to cancer," National Sports Institute (NSI) chief executive officer Dr Ramlan Abdul Aziz told Malaysia's New Straits Times daily on Wednesday.
Dr Ramlan said it was unhealthy to play matches if the Air Pollution Index (API) was over 100 and the paper said Tuesday's Super League match between PKNS and Selangor went ahead on the outskirts of Kuala Lumpur despite a reading of 252.
