Europe seen higher after Draghi comments

European equities are expected to open higher Friday after the European Central Bank's President Mario Draghi reiterated the bank's commitment to its 1 trillion euro ($1.14 trillion) bond buying program.

The ECB will "implement in full" its bond-buying program, the bank's chief Mario Draghi said on Thursday, and it will stay in place "as long as needed."

"While we have already seen a substantial effect of our measures on asset prices and economic confidence, what ultimately matters is that we see an equivalent effect on investment, consumption and inflation," Draghi said, according to the text of a speech delivered in Washington.

"To that effect, we will implement in full our purchase program as announced and, in any case, until we see a sustained adjustment in the path of inflation.

Meanwhile in Asia, stocks turned mixed after Chinese shares fell Friday, shrugging off an impressive lead from Wall Street overnight. U.S. major indexes rallied one percent higher each on Thursday on the back of calmer bond markets and a weaker dollar.

Greece remains in focus as talks over reforms-for-aid continue between the country and its lenders. Offering a privatization concession to its creditors Thursday, Greece appeared to push ahead with the sale of its biggest port, Piraeus.

One of Greece's lenders, the International Monetary Fund, said on Thursday that it remains flexible in debt talks with Greece and hopes international creditors can reach a deal with Athens soon, Reuters reported.
