CLSA, an institutional broker and investment group, has proposed moving its flagship investors’ forum from Hong Kong to Singapore this year as pandemic restrictions in the territory disrupt international travel, according to two people familiar with the matter.

They said the brokerage had suggested to its Chinese owner Citic Securities the relocation of what is Hong Kong’s best-known business conference. The star-studded annual event has run for almost three decades with attendees including representatives from the world’s biggest funds and celebrity guests such as Bill Clinton, Desmond Tutu and Kylie Minogue.

CLSA’s proposal to move the event, typically attended by 1,500 institutional investors from around the world, highlights the disruption caused by Hong Kong’s strict pandemic control measures.
