The Chinese economy grew 6.9 per cent in 2015 -- the slowest rate since 1990 -- and capital has been flowing out of the country due to worries over flagging growth, causing the currency to weaken.
"International speculative forces have recently focused on shorting China," People's Bank of China governor Zhou Xiaochuan said, according to a transcript of the interview posted on the bank's website yesterday.
"They are eager to manufacture public opinion to try to force an outcome as soon as possible," he said, but did not identify them.
In early January China guided the yuan -- also known as the renminbi -- down by setting its daily fix lower for eight consecutive sessions, representing a 1.4 per cent fall, before it returned to stability.

The falls raised fears of a creeping devaluation, as it echoed moves in mid-August when China adjusted the yuan down nearly five per cent over a week.
Zhou vowed China would use its massive foreign exchange holdings to defend the yuan.
The country's foreign exchange reserves dropped USD 99.5 billion to USD 3.2 trillion in January, according to official figures, as the central bank sold dollars to slow the slide in the yuan.
But Zhou said: "There is no foundation for continued depreciation (of the currency)."
He pledged that currency reforms would continue despite the turmoil although the government would maintain its management role. China keeps a tight grip on the yuan on worries free capital flows will bring financial risk and reduce its control.
