After hitting a three-week high, the dollar retreated into negative territory, while the Chinese yuan jumped after China's central bank said it would keep the currency "basically stable". The bank also said it would take counter-cyclical measures to keep foreign exchange markets stable based on market conditions. MSCI All-Country World Index .MIWD00000PUS , which tracks shares in 47 countries, was up by 0.1 percent after the start of European trading, and set to break a four-week streak of gains.
While a tech-led rally on Wall Street overnight filtered through to Asian stock markets, gains were capped by the trade tensions. MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was up 0.05 percent, though it was down over half a percent on the week.

Elsewhere in currencies, Britain's pound reversed course from two-week lows to turn higher on the day. It had earlier fallen after Bank of England Governor Mark Carney said there was an "uncomfortably high" risk of Britain leaving the European Union without a deal. GBP/ BoE raised interest rates from crisis-era lows this week but that failed to boost the pound as the British central bank also signalled it was in no rush to tighten policy further.

"Clearly, this is about the fear that Tria gets kicked out, which could lead to a collapse of the government, new elections, and the League gaining even further," said Commerzbank (DE:CBKG) strategist Christoph Rieger.
"Or it may mean that they agree on a budget that's at odds with the EU," he said, adding that this would imply heavier borrowing and greater bond supply.
