The UK government said the renewable industry had sought is view on the use of the proposed turbines in British waters and energy system.
A spokesperson said: “After careful consideration, government’s view is that we cannot support the use of them in UK offshore wind projects.
“We will always act to protect our national security, and we are committed to strengthening and prioritising resilient and sustainable offshore wind supply chains.”
They added: “We welcome investment from China where it’s in our national interest – as demonstrated by significant inward investment during the prime minister’s recent visit to Beijing. 
“We will continue to take a consistent, long term and strategic approach to our relationship with China – cooperating where we can, whilst never compromising on security and resilience.”
Scotland’s Deputy First Minister Kate Forbes said national security was important and must be respected.
But she added that it was “regrettable” the UK government had not explained precisely what the problem was with Ming Yang.
Forbes said: “This decision has been sitting on the desks of UK government ministers for over 18 months – their dithering will have far-reaching consequences that, once again, will be left for Scotland to deal with.
“That is simply sabotage of Scotland’s industrial future.”
