What made the business news in Asia and Europe this morning? Here's our daily business round-up:
Glencore raised its offer to 3.05 of its shares for each Xstrata share, from the 2.8 previously offered.
Qatar Holding, which owns about 12% of Xstrata, had said it would block the merger as it wanted a ratio of 3.25.
Earlier, Glencore had delayed Friday's shareholder meeting to vote on the original proposal.

Under the old deal, Mr Glasenberg would have become deputy chief executive of the new business.
