On Saturday, US national security adviser Robert O'Brien said an initial trade agreement with China is still possible by the end of the year, though he warned Washington would not turn a blind eye to what happens in Hong Kong.

"Markets are showing some signs of tiring of the steady drip feed of upbeat comments from US officials and no signs of a final agreement looking likely," said Robert Rennie, head of financial market strategy at Westpac.

"Key for markets will thus be whether the Dec. 15 tariffs covering approximately $156 billion of largely technology imports are postponed and whether a deal can be signed ahead of that date, with press suggesting that these tariffs will be delayed to give negotiators more time."
Reuters reported an ambitious "phase two" trade deal was also looking less likely, according to US and Beijing officials, lawmakers and trade experts.

"For the EU data, the important takeaway was the ongoing decline in the manufacturing sector is now spreading to the larger services sector, a worrying sign for the global economy."
