Europe looks set to firmly condemn Egypt's blistering violence but may stop short of sanctions against the country when EU foreign ministers convene for emergency talks Wednesday, keen to keep channels open with Cairo.

Almost all 28 European Union foreign ministers are expected at the 1100 GMT talks, hastily convened in the middle of Europe's summer break after the deaths of almost 900 people in a week of unrelenting violence.

Ministers will examine a range of options set out by EU foreign policy chief Catherine Ashton, who remains in close touch with players across the spectrum and who last month was the first foreign official to meet ousted Islamist president Mohamed Morsi in his secret detention centre.

Ashton told journalists on the eve of the talks that she had told the government she was ready to return to help facilitate a political solution to the crisis. "I would be more than willing to go back to Egypt if they wish me to come back," she said.

Among the options mulled by the ministers will be withholding part of the EU's massive aid package or suspending arms deals as well as military and security cooperation pending a political solution in the Arab nation.

Some EU countries, notably Germany and Italy, have already suspended arms exports. Denmark has cut off funding for development projects run directly with the government or with public institutions.

Dutch Foreign Minister Frans Timmermans urged the powerful EU bloc to stick to its principle of "more aid for more democracy", or as he put it "in this case less-for-less".

"The Netherlands wants the means at the EU level for further suspending aid and the criteria for possible resumption," he said in a note to parliament.

But he added that "lines of communication with both the authorities and the opposition must be kept open so that the EU can exert sufficient influence and have enough leverage."

Senior EU diplomats in private warn against cutting aid that currently for the most part is channelled to grassroots groups working to reduce poverty or improve rights.

"We will respond to the current situation," the European Union's special envoy to Egypt, Bernardino Leon, said this week. "But at the same time we will remain a constructive actor trying to promote a political solution."

"There is no easy solution," Leon said.

Aid at stake amounts to nearly five billion euros ($6.7 billion) in loans and grants promised by the world's top aid donor to Egypt for 2012-13.

It includes one billion euros from the EU with the rest from the European Investment Bank and the European Bank for Reconstruction and Development.

But because EU aid was made contingent on political and judicial reforms after the 2011 uprising that overthrew Hosni Mubarak, little to no direct aid has been approved since 2012 due to lack of progress.

Military assistance however amounts only to 140 million euros a year, well below US defence aid.

Saudi Arabia thumbed its nose at the threat of sanctions against Egypt, pledging on Monday that Arab and Islamic countries will step in to help Egypt if Western nations cut aid.

A French diplomat speaking on condition of anonymity said "should we decide to suspend this or that project we risk penalising Egyptian people above all. We could also review defence or security agreements but even that is complicated."

"We can't act as if nothing has happened, but at the same time we need to be careful not to be counter-productive."

EU foreign ministers have not met since July 22, when they urged Egypt's army to stand aside and allow a peaceful transition to civilian rule following the military overthrow of Morsi.
