Hong Kong citizens arriving in the UK under the British National Overseas (BNO) Passport scheme will receive a £43m support package to help them settle.
The programme will help new arrivals access housing, work and educational support.
Twelve "virtual welcome hubs" will be set up across the UK, offering "practical advice and assistance in applying for school places, registering with GPs and even setting up businesses."
In January, UK ministers introduced a new visa system to make it much easier for millions of people in Hong Kong to live and work in the UK.
In response, the Chinese government said it would no longer recognise the BNO passport and that it "reserved the right to take further action".
