Cambodian government must respect human rights. People are free to demonstrate peacefully. They should not be stopped just because of different political views. Rather, government should responsibly offer a good care to their own citizens because it is their only role. In addition, peaceful methods such as negotiation, compromise must be put so that conflict are avoided. Yet, such act of violence done lately is completely contrary to above principles. They should go back to the table fairly and openly discuss what to be done to bring greater interests for whole Cambodians.
By whatever mean, discussion is the only approachable solution for all parties in Cambodia. They should put Cambodian interests above all. They should not using violent forces against civilians and innocent people. Rather they should come together and put all issues on the table and begin their negotiation. Because all parties claim to defend Cambodian and national interests, there must be a room for compromising and there must be available options for all involved parties to work together to reach their ended goals.
As far Human Rights is concerned, the ruling government must not use force to depress or put pressure on the opposition parties to reach the deal. From fair competiton, they should accept the result and since their national allows them to recount the ballots, they should do so in a case of unproper during national election. Nothing will be worse, if the result shows the same or different since the opposition or the ruling party win, they would lead to country to better, too. That's their ended goal. Or is it because they wanted to rule the government because they could earn lots of money?
They may be able to earn lots of money from their position but what will be the next result in the next national election? They won't be able to stay in power anymore. People and everybody knows that. They can't hide it.
