Hello. I'd urge you to contact (in Singapore) the Australian, British and American Embassies. All three have Embassies in Yangon (the Americans do not have an Ambassador however (last time I looked) as they are not happy with the Junta. The Brits are very outspoken about things and the Australians less so. You should use the Embassies in Yangon to assist you in your objectives in Myanmar. They are however very wary of foreigners who may have alterior motives in their goodwill gestures however sincere they are.
You may also contact the Honorary Consul General In Yangon for The Netherlands, his name is U Hla Tun and is a very nice (but now quite elderly) statesman who will also be helpful to you as he is "local". He is the local Agent for one of the Big 5 international accounting firms in Yangon and can be contacted via The Netherlands Embassy in Singapore or Bangkok.
Good luck.
