> China grants up to 200% tax deduction on intangible assets acquired through R&D. Means your spending on AI training fees becomes a tax return amount or like appears as a magical donation deductible on the books.

This is misleading. Deduction reduces taxable income and does not provide tax return. E.g. if your taxable income is $1000 and you spent $100 on R&D and qualify for those 200%, $800 will be taxed.
