Tax Relief for Withholding Tax

Dear Sirs, I’m now consolidating data for self assessment reporting. One point regarding stock dividend I would like to clarify of my understanding beforehand. In the tax year 2023-2024, I’ve got dividend for the following types of stock: (1) nos. of shares for Hong Kong stock that I purchased through Hong Kong Stock Market but the Company registration is in China so 10% of withholding tax has already imposed (i.e. Already deducted 10% for China tax before dividend distribution as marked in the statement) (2) nos. of shares for US stock that I purchased through Hong Kong Stock Market but the Company registration is in United State so 30% of withholding tax has already imposed (i.e. Already deducted 30% for US tax as marked in the statement) Per the information I’ve got from HMRC website, there is a “Double Taxation Agreement” in-between Hong Kong and UK so does it mean that I can claim the tax relief for the exactly withholding tax amount which has been deducted and reflected in my statements? If yes, would you please advise how can I input in self-assessment form? Thanks.
