The euro held above a three-week low on Monday as improved Chinese factory activity lifted sentiment, with the Australian dollar leading gains by nearly half a percent.
Investors are scrutinizing economic data this week for signs of economic slowdown in Europe, while key votes on Brexit mean further volatility in sterling is likely.
Risk appetite grew after China's official purchasing managers' index (PMI) released on Sunday showed factory activity unexpectedly grew in March for the first time in four months.
The positive readings pushed the Australian dollar, often seen as an investment proxy for Chinese economic prospects, 0.4 percent higher to $0.7126.
The Chinese yuan gained a quarter of a percent in offshore trade to 6.707 to the dollar.
Traders braced for a raft of economic data set to show the euro zone economy on hold, with inflation, unemployment, and manufacturing PMIs all largely flat on their previous read-outs.
The euro struggled near a three-week low of $1.1210 brushed on Friday. The single currency was last trading up 0.1 percent at $1.1232.

The quest for a way out of the Brexit stalemate continues on Monday evening when British lawmakers will vote on alternatives to Prime Minister Theresa May's EU withdrawal agreement.
The two alternatives with the widest support are keeping Britain in a customs union with the European Union, and having any outcome validated by a second referendum - both of which are anathema to large parts of May's Conservative Party.
Sterling was a shade high at $1.3060, still within sight of Friday's near three-week low of $1.2977 and not far from last month's low of $1.2945.
The greenback rose 0.4 percent to 124.79 yen, extending its advance from the 1-1/2-month low of 109.70 it touched a week ago to 1.3 percent.
Positive risk sentiment helped boost emerging market currencies. The Mexican peso gained 0.35 percent to 19.364 to the dollar while the South African rand tacked on about 0.8 percent to 14.395 per dollar.
