He later joined the Fiji Ministry of Foreign Affairs, where he quickly established himself as a skilled negotiator and policymaker. During the 1980s, he held several diplomatic assignments abroad, including a key role in establishing Fiji’s embassy in Tokyo, Japan, and serving as Consul General in Sydney, Australia.
