The euro climbed to a one-week high against the greenback on Thursday, boosted by news that Asian investors, particularly China, showing interest in buying Portuguese bail-out bonds that will be issued in mid-June.

EUR/USD advanced to a one-week high of 1.4196 during European late morning trade. The pair is likely to find support at low of 1.4001 and resistance at 1.4345.

The euro advanced 0.65 percent to $1.4180 against the dollar, gained 0.51 percent to Y116.06 against the yen and rose 0.41 percent to £0.8692 against the pound.

The Single Currency was given a boost after a Financial Times article quoting the chief executive of the European Financial Stability Facility as saying China was interested in buying bonds for the Portugal bailout, to be issued in mid-June.

Adding to support, stronger commodity prices also helped buoy the Euro. Crude oil futures gained to above $101 a barrel level on Thursday as increased fuel demand in the U.S. and weaker dollar buoyed sentiment.

However, uncertainty over whether Greece would need to restructure its debt and undertake new austerity measures and the potential for contagion affecting the likes of Spain and Italy will limit gains.
