Dealing in Vanuatu is a tough business. The expat's and overseas investors have termed the phrase "the Vanuatu factor". It basically means keep your own counsel and be very wary of who you trust. I suppose its understandable as they have seen governments come and go and yet the local people here are still trying to struggle on $5-$8 wage a day. So much for their 25th independence day celebrations. Many locals have to work for uncaring and sanctimonious bosses. Some which readily accept the term "master" from their employees.
Is it any wonder that a chance to renegotiate a deal is recreated, and more money is asked for, whether be for their land or a building contract, a show of aloofness, a dispute, and or confusion, is a good tactic. This method is quite common throughout third world countries, whether it is intended or not it works. Lets face it most locals lose from development coming from some self serving, oportunistic expatriate.
When dealing with the Vanuatu people try and be precise and clear. Have all documents authorised and signed by the appropriate party's. Only deal in trusts so money is not transfered until contracts are filled. Always have a back up plan if possible with other options.To create a sense of haste from the vendor or group.
It's not rocket science and these principles are the same the world over. Remember most vendors want the most for their land or company,and most purchasers want as little to leave their wallets as well.
If however you want to just take in the sites or maybe get yourself a nice picture of Vanuatu, island posters might just have the picture you need.
