||This phylosector comprises 22 sets of languages spoken by communities in eastern Asia, from the Himalayas to Manchuria (Heilongjiang), constituting the Sino-Tibetan (or Sino-Indian) continental affinity. See note on nomenclature below. 70= TIBETIC phylozone 71= HIMALAYIC phylozone 72= GARIC phylozone 73= KUKIC phylozone 74= MIRIC phylozone 75= KACHINIC phylozone 76= RUNGIC phylozone 77= IRRAWADDIC phylozone 78= KARENIC phylozone 79= SINITIC phylozone This continental affinity is composed of two major parts: the disparate Tibeto-Burman affinity (zones 70= to 77=), spoken by relatively small communities (with the exception of 77=) in the Himalayas and adjacent regions; and the closely related Chinese languages of the Sinitic set and net (zone 79=), spoken in eastern Asia. The Karen languages of zone 78=, formerly considered part of the Tibeto-Burman grouping, are probably best regarded as a third component of Sino-Tibetan affinity. Zone 79=Sinitic includes the outer-language with the largest number of primary voices in the world, representing the most populous network of contiguous speech-communities at the end of the 20th century ("Mainstream Chinese" or so-called 'Mandarin', standardised under the name of Putonghua). This phylosector is named 7=Sino-Indian (rather than Sino-Tibetan) to maintain the broad geographic nomenclature of all ten sectors of the linguasphere, composed of the names of continental or sub-continental entities. The future nomenclature of the Sino-Tibetan affinity itself remains a matter for public debate and consensus, although it should be observed that languages from 8 of 10 zones in this phylosector are currently spoken in geographic India. More important, however, is the need for further geographic surveying and comparative analysis in this phylosector, which in Southeast Asia includes a number of geographically fragmented and interspersed speech communities.
