Sugestão.

Acredito que a melhor tradução para o português seja o termo "conflito de interesses"

What is involved in a person being “brought over the wall/crossing the wall”?

It usually means a person who usually does trading or sales or research working on a project where they have some inside information, and therefore (for the duration of the project) they are not allowed to publish research or do their normal job, because they would have a conflict.

***potential conflicts of interest ***

não queremos ficar restringidos/limitados na (nossa) informação / comunicação sobre/por causa de qualquer entidade cotada em bolsa

Penso que o sentido é este, (passar para o outro lado) não querem ficar limitados por passarem para uma posição em que vão ter acesso a informação de algum modo impeditiva/restritiva da atividade que desenvolvem.

Chinese Wall
 "Chinese Wall" policy demarcates “inside areas” from "public areas".
 Those areas having access to confidential information, considered “inside areas” and areas, which deal with sales / marketing / investment considered "public areas".
 The employees in the inside area shall not communicate any Price Sensitive Information to anyone in public area.
 In exceptional circumstances, employees from the public areas may be brought "over the wall" and given confidential information based on "need to know" criteria, under intimation to the Compliance Officer.
