Every article you read about technology here is likely very tentative and far from proven for real-world usage. No doubt a 'few' Chinese Scientists will be ordered to investigate its potential as a practical alternative to parts of their 'rare-materials' industry... but they won't be running around in a panic until it becomes even a modest possibility.
