I am currently living in a country where there's only a handful of Malaysian here. There are 5 families in Lagos plus some blokes who are on various assignments with some of the multi-national companies based in Lagos. In the mix, we have Shiela Madu who married a local man many many years ago.
In Abuja, there's about the same number of us, but from time to time; Khairy from Matrade office in Lagos would announce there are Malaysian currently in Nigeria on attachment as consultants to some other international or reputable local companies in other locale (e.g Port Harcourt, Calabar etc).
Since there's only several of us here, we know each other quite well and always within contact; just to be on the safe side. 3 years in Nigeria had thought us a lot on being constant contact within the group. Like I mentioned to prospective business group back in Malaysia, it's generally safe but like everywhere else; things can go wrong. So, it's best in to be in contact with the rest of Malaysian here, staff of the High Comm included.
