David Cameron said he would "stick with the facts and figures" after a scathing editorial in Chinese newspaper The Global Times dismissed the strategic importance of the UK and his "ice-breaking" visit.
Speaking during his visit to Shanghai, the Prime Minister said: "This is a visit that has delivered almost £6 billion-worth of deals.
"It is a visit that comes on the back of an eighteen month period where we have seen more Chinese investment into Britain in the last 18 months than in the previous 30 years.
"And also it is a visit where we have seen very good, high level, substantial discussions both with the premier and with the president - the premier who described the partnership 'as indispensable'. So I will stick with the facts and the figures."
The Global Times newspaper's criticism of the UK is stinging given that David Cameron has spent two days courting China's leaders.
David Cameron's visit to China has not been easy to arrange with the pressure for the trip coming from the British.
David Cameron hopes to mend relations with China as he brings a large trade delegation with him.
