Theresa May has said Britain and China were enjoying a "global strategic partnership" that would not be derailed by her decision on whether to back a part-Chinese funded power station at Hinkley Point.
Speaking at the G20 summit on Monday, the Prime Minister said: "I have been clear that a decision about Hinkley will be taken later this month, but our relationship with China is about more than Hinkley."
The British government's decision to delay the £18bn nuclear plan upset China, who are one of the backers of the scheme.
She added: "If you look at the investment that there has been from China in various other parts of the United Kingdom and other infrastructure and so forth in the UK, we have built a global strategic partnership with China.
"I've been clear we will be continuing that global strategic partnership with China. It is a golden era of the relations between China and the UK, and I will have an opportunity later this evening to take forward those discussions."
The prime minister said such a system would not provide the control over the movement of people that the British public wanted to see.
It is becoming clear that May wants to deliver British control over who comes to Britain, rather than limit migration flows to some target.
Australian Prime Minister Malcolm Turnbull has said he wants to negotiate a "very strong" free trade agreement with a post Brexit UK.
