India became Sri Lanka's top tourism generating market after visa restrictions were lifted by Sri Lanka about a decade ago, restoring freedoms that existed before Western practices aimed at reducing human freedoms were imported to the region.
Sri Lanka re-introduced visas for Indian visitors at the beginning of this year, as visa on arrival facility for many countries were ended amid rising nationalism in the island despite the end of a 30-year war.
The electronic travel authorization process has eased the entry for citizens of some countries by eliminating paper work and cutting processing time.
India's rupee has also weakened, making overseas travel more expensive, though Sri Lanka's rupee has also fallen about 16 percent over the past several months.
Unlike the Association of South Asian Nations which created a visa free region triggering a tourism and aviation boom, the South Asia Association of Regional Co-operation has not been able to provide significant freedoms to the region's citizens.
Sri Lanka however unilaterally lifted visas for Indian visitors about decade ago, with officials also persuading India to allow private Indian carriers to fly to the island, in a ground breaking regional liberalization of aviation.
Visas came into wide use after World War II ending centuries of travel and immigration freedoms enjoyed by human beings around the world.
Ironically, countries which pioneered the imposition travel restrictions in Europe have now created a visa free region as part of restoring the four freedoms -good, capital, service, and people - that were lost due to rising nationalism, fascism and socialism in the region.
