Planting Sinhalese, encouraging mixed marriages, etc. through financial rewards
The oath was given on a different sheet of paper for each language. The mischief was that the oaths were different in the Sinhalese and Tamil languages. While the English and Sinhalese seemed innocuous, the Tamil version reflecting the world view of the new government, got employees to swear to being moulded into one ethnic group. It seemed to portend doing with greater vigour that which Sinhalese nationalists are already doing in the North and East: planting Sinhalese, encouraging mixed marriages, etc. through financial rewards. As openly stated by the rabid nationalists including a former presidential candidate in 2010, Tamils are welcome only so long as they agree that this is a Sinhalese country. That is Tamils must agree to be moulded into the same people as the Sinhalese, changing religion and intermarrying. The idea is common to the two big political parties in Sri Lanka.
