Switzerland is due to make overdue payments to the fund and the country’s scientists have, consequently, been barred from Horizon Europe.
Swiss politicians have shown a willingness to resolve the conflict by paying contributions to the fund.
According to Ms Gabriel, this will pave the way for Switzerland to rejoin the programme.
Ms Gabriel said: “There are three stages – payments for the cohesion funds, a global accord, and concrete ways of participation.
“It’s an ongoing progress which, for now, remains suspended.”
