In early 1962, JCI Senator John Leong was invited by JCI Senator Sim Kheng Lung to attend a JCI Conference in Kuching. After his return from Kuching, JCI Senator John Leong invited a group of 13 young men together, whose names are noted below, to the 4th Divisional Youth Council building for the discussion about the formation of Miri Chapter of the Junior Chamber of Commerce:
| Foo Chia Choon |
| Chong Fung Ping |
| James Ting |
| David Chia |
| Ling Uong Leh |
| Dicken Tan Boon Kim |
| Abdul Rasul Khan |
| D.A. Dwason |
| Kwan Chee Ming |
| Yong Chon Yee |
| Andrew Foo |
| Leong Chee Seng |
| Sim Teck Sing |
A very successful meeting was held, with everyone attending agreeing to form the Chapter unanimously.
The Chapter was subsequently registered on 24th October 1962 with JCI Senator John Leong as its Chartered President for a duration of four years. In 1963, he was awarded the JCI Senatorship and became the first JCI Senator in Miri.
The name of Junior Chamber of Commerce was changed to Jaycees during 1972 JCI World Congress in Taipei. Accordingly, Miri Junior Chamber of COmmerce was renamed to "Miri Jaycees".
Over all these years, Miri Jaycees has produced quite a number of good and efficient leaders, some of whom are now holding important positions in our community such as JCI Senator John Leong (Bishop), Datuk JCI Senator Dr George Chan (Deputy Chief Minister), JCI Senator Chong Kuan Kee (MMC Councillor).
