The UK government has allocated £1.2bn of funding to the Welsh government, bringing the total to £4bn this year to deal with the COVID-19 pandemic.
Some 480,000 Welsh jobs have been supported through the Coronavirus Job Retention Scheme and the Self-Employment Income Support Scheme.
Meanwhile the Plan for Jobs and Job Retention Bonus have provided funding to decarbonise public sector buildings, including social housing.
Simon Hart, secretary of state for Wales, said: “The UK government is committed to doing everything it can to defeat coronavirus, and this additional funding for Wales – now worth £4bn – will help the Welsh government in delivering its response on the front lines.
“This guarantee from UK government means that the Welsh government can invest to protect jobs and plan for Wales’ economic recovery.
“We will continue to work closely with them to ensure we can move forward together as well as providing additional economic support for workers and employers through the range of measures announced by the Chancellor.”
