Thai Prime Minister Yingluck Shinawatra told Sri Lanka's parliament Friday the two countries should work together to strengthen Buddhism as a religion and as a way of life.
Yingluck, in Colombo on a two-day visit to commemorate the 260th anniversary of Sri Lankan Buddhist monks obtaining higher ordination from Thailand, followed her brother in addressing parliament.
Then Prime Minister Thaksin Shinawatra addressed parliament in 2003 on a visit to commemorate the 250th anniversary of the same event.
Yingluck added both Sri Lanka and Thailand deeply value democracy, which "is not an internal affair" of any one country.
She also had talks with President Mahinda Rajapaksa and will also visit Kandy, the country's hill capital 115 kilometers northeast of Colombo where the chief monks of the Siamese sects of Sri Lanka's Buddhist clergy reside.
Sri Lanka and Thailand follow the Theravada tradition of Buddhism, considered the more orthodox form of the religion.
Yingluck will be also signing bilateral agreements on tourism, science and technology during her stay in Sri Lanka.
