evidence: Stung Treng provincial governor Svay Sam Eang on July 9 led officials and youth groups to plant palm seeds along the Cambodia-Laos border as part of efforts to preserve territorial integrity and benefit future generations by teaching them about their national identity. [...] He said Stung Treng does not have as many palm trees as Takeo and Kampong Speu provinces, but after many border posts had been placed along the border, provincial authorities had initiated planting operations. [...] According to Theavy, more than 250km of the province borders Laos. Provincial authorities had planted about 100km of them.
