The deal was signed April 7 in Minsk by the heads of the two countries' public broadcaster TVs.
"LTV has grown in the same way Belarusian TV has. That's why we'll be able to cooperate easily in our joint European information space. I see only bright perspectives ahead," said Gennady Davydko, head of Beltelradiocompany.
While LTV head Ivars Belte sounded similarly pleased about the agreement.
"A lot of what's happening in Belarus is interesting to Latvian nationals. I think that the agreement opens many doors - if not big, then small ones - that will pave the way for a cooperation of a new sort," said Belte.
The deal could also include cooperation in several different projects.
Previously the deal was pondered by diplomats from both sides. Rus.lsm.lv reported in January that both countries could be exchanging, for example, movies from the neighboring state.
Many Belarusian programs are shown in Russian, an official language in Belarus. The programs could be translated or appear in the original, contributing to broadcasts of Russian-language content in Latvia.
"But it's more likely that it would happen both ways," Foreign Ministry Press Secretary Raimonds Jansons told Rus.lsm.lv in January.
