Nevermind that half of a nation's export or a quarter of a nation's revenue from a single source is a ridiculous amount, the money norway uses to play neocolonist comes from their sovereign wealth fund(s) which come entirely from oil.
Also, indonesia ( and ASEANs ) problem is poverty, education and economic development. That $1 billion is nothing in the greater scheme of things. Heck it probably made things worse because deforestation went elsewhere, indonesia's development was slightly stunted and indonesia will probably deforest at a greater rate in the future.
Maybe if norway truly cared, they will force netherlands to pay reparations for colonization to indonesia and hand over the assets of the largest oil company in the world ( royal dutch shell ) to indonesia so that indonesia could develop faster. The dutch got rich stealing oil from indonesia. Maybe return some of that back?
Or buying $1 billion in advertising for self-congratulatory purposes while making things worse is better.
What has fundamentally changed? Nothing. It's like a billionaire tossing a homeless man $1 and being celebrated for their charity. Especially so if the billionaire caused a financial crisis that cause the guy to lose his job, home and become homeless in the first place.
I'm sure the indonesians living in poverty are ecstatic that wealthy norwegians are using their oil money to toss them some crumbs.
