When you talk about what the percentage of Yttrium is in nature, it's probably different in other countries/regions
Vietnam is a top exporter (now) of scandium and yttrium. More than China? hard to believe.
The top exporters of Rare-earth metals, scandium and yttrium are Vietnam ($113M), Australia ($69.8M), China ($66.5M), Hong Kong ($49.5M) and Thailand ($19.2M). The top importers are Japan ($180M), Malaysia ($70M), Singapore ($48.5M), Thailand ($8.01M) and the United States ($4.3M).
