Why is Vale's dividend so high?

I'm curious to understand why Vale's dividend yield stands out as being particularly high. Could it be attributed to the company's robust financial performance, allowing them to distribute a generous portion of their earnings back to shareholders? Or perhaps there's a strategic reason behind the decision, aimed at attracting and retaining investors? It would be insightful to delve into the factors influencing Vale's dividend policy and understand what sets it apart from its peers in the industry.
