Fabian Maienfisch, spokesman of the economic affairs department, told AFP news agency on Wednesday that Bern would follow developments and potentially reverse the decision in the future.
The Swiss government halted arms exports to Saudi Arabia in 2009 but was until now supplying the kingdom with spare parts as well as munitions for air-defence systems and firearms for private use.
Khashoggi, a 59-year-old Saudi journalist and Washington Post columnist critical of Saudi Crown Prince Mohammed bin Salman, was killed after entering the consulate in Istanbul on October 2.
Gruesome reports in the Turkish media had previously alleged that Khashoggi had been killed and cut into pieces by a team sent from Riyadh to silence him. His body is still missing.
After initially insisting that Khashoggi left the consulate unharmed, then saying he died in a brawl during an interview, the Saudi government ultimately admitted he was killed by a “rogue operation”, and arrested 18 people.
The case has sorely strained relations between Saudi Arabia and the West and has fuelled international debate about arms deliveries to the ultra-conservative kingdom.
