Taxes for nri

I am currently an Indian National and planning to move to Kigali, Rwanda in January 2017. There are few questions which I had. 1. Would I have to pay taxes to Govt. of Rwanda as well as Govt. of India both ? I read somewhere that India and Rwanda do not have Double Tax Avoidance Agreement. 2. If have an account at a Bank in Rwanda and my employer transfers the money there, could the same amount of money be transferred to my NRE account in India. Will this involve in transaction charges ? Another option given by my employer is that I can work in Rwanda, however I can open by Bank Account in the United States 1. Is this legal to do so ? 2. If I open my Bank Account in the US and work in India , can I take advantage of Double Taxation Avoidance Agreement ? 3. I have invested in some mutual funds already in India. Can I continue to invest in them considering FACTA ? 4. Again, if I want my parents to use money from my account, does transferring money from my American account to NRE account incur transaction charges ?
