Chinese data that provided a bit of something for everyone kept Asia largely in check overnight, but Europe started well with only London's FTSE .FTSE lagging as the pound's power weighed on its big exporters. .EU
There were more signs of China opening up its economy too and a steadier Russian rouble RUB= showed investors were also gradually shifting attention away from Syria tensions back to corporate earnings and possible interest rate moves.
The pound's GBP=D4 rise was its eighth in a row, coming as bets firm on another Bank of England rate hike next month, while yields on U.S. Treasuries were at their highest in over three weeks ahead of a flurry of top Fed speakers. GBP/

This is encouraging," said Robert Subbaraman, chief economist for Asia excluding Japan at Nomura in Singapore.

Commodity markets were still focused on the geopolitical situation in Syria and the fallout from the U.S. sanctions on Russia.
Buoyed by growing expectations over tighter supply in the aftermath of sanctions on major Russian producer Rusal, aluminium prices jumped more than 1 percent to almost $2,500 a tonne to hit their highest since mid 2011. MET/L
Rusal accounts for 6-7 percent of global aluminium supply.
Oil steadied at $66.57 a barrel CLc1 for U.S. crude and $71.66 a barrel for Brent having tumbled nearly 1.8 percent overnight as concerns over Middle East tensions eased. O/R

It was curbed slightly too after data showed wage growth stalled last month despite the unemployment rate hitting a four-decade low. President Donald Trump's comments on Monday about China and Russia trying to devalue their currencies continued to weigh on the dollar, with investors believing that the U.S. administration wants a weaker currency.
