Personally, I see the following: Western countries are trying to prevent the growth of Chinese influence in Cambodia and prevent a large project to build a power plant on the Mekong - a river in the basin of which there are already 26 power plants in China, 56 (!!!) power plants in Laos, 1 power plant in Myanmar, 5 power plants in Thailand, 18 power plants in Vietnam, and only one (1) power plant in Cambodia.
Currently, more than 50% of Cambodia's electricity is generated by burning coal or oil. And these “activists” are protesting against the construction of a hydroelectric power station on the river, where there are already 97 other power stations. https://en.wikipedia.org/wiki/Hydropower_in_the_Mekong_River_Basin
They are protesting in one of the poorest countries, which is forced to constantly import electricity, which critically slows down the country's development. They are protesting against a hydroelectric dam in the country that, due to electricity shortages, has increased the burning of coal and oil to generate it by 40% over the past 10 years.
Why am I not surprised that Mother Nature Cambodia is a foreign NGO, supported by foreign funds, and the leader of this organization is a 35-year-old foreigner (Spanish) who fled Cambodia before trial?
And one more thing: I wonder why CNN didn’t mention that among the accusations was insulting the king?
Therefore, my opinion is that these children are victims of global geopolitics, in which it is beneficial for politicians to keep Cambodia weak and dependent on Western loans and grants and away from Chinese influence.
