yes,my myanmar's dict from their goverment says there are 4 tones in their language.But in their dict or other myanmar dict from the west,there are no words like chinese and thai,laos with one word exactly same vowel and consonant but with different tones.
So I cannot consider myanmar is a tonal language.By the way,myanmar script is from Mon which isn't burmese own invention.
Myanmar/tibetan are both tonal languages. In fact both these groups are genetically related to the chinese which was separated from each other many thousand years ago.
The sino-tibetan (which are all tonal and monosyllabic) consists of 3 branches:
1. sino branch - min, wu, mandarin, cantonese, hakka etc
2. tibetan/burmese
3. tai, laos
We are debating whether vietnamese belongs to the tai branch which has the characteristics of adjective after noun eg. chicken male instead of male chicken.
The writing system doesn't dictate the language family (tai obviously borrowed from sanskrit, an indian language). I suspect the same goes for burmese and mon languages (though not certain about this) due to the indian influence in the past (buddhism).
