The Olympic Council of Malaysia (OCM) will have a briefing for the associations on their participation.
The Commonwealth Games will be held in New Delhi, India from Oct 3-14, while the Asian Games will be in Guangzhou, China from Nov 12-27.
"We will brief all associations on the list of their athletes," OCM secretary Datuk Sieh Kok Chi told Bernama Monday.
"This is not the first time we have done this and it is hoped that all sports associations are perceptive to the set guidelines," he said.
"Meanwhile, the OCM selection committee will meet on May 31, June 1 and June 2 to determine the number of athletes for both games," he added.
Sieh said on the average at least 230 athletes and officials were expected to represent the country for the Commonwealth Games and about 400 athletes and officials for the Asian Games.
