The government provides 60% of the tuberculosis budget and donors provide 40%. Use of a regionalisation system, with each region receiving support for tuberculosis activities from an individual donor, avoids duplication of activities from direct donor funding. Thailand, which finances tuberculosis services through a plan for universal health coverage, has strategically used additional domestic financing from external sources to fill gaps in tuberculosis control, for example to support needs of migrant populations. External funding provides more than 50% of financing for tuberculosis control in Vietnam, aligned to the Medium-term Tuberculosis Control Development Plan to ensure coordinated investment, but donors maintain several project coordination units that manage various projects funded by donors.
