The Eastern Partnership summit will take place in Brussels on Friday (24 November). The leaders of the EU 28 member states will meet with those of the six partner countries: Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine. A lot of work has gone into preparing for the summit, in order to avoid the problems seen in the previous summit in Riga in 2015, and also to address a number of issues that are likely to be divisive.
There remains however one big question that overshadows the meeting - the extent to which the European Union is open for closer relations with those Eastern Partnership countries that want this.
Much has happened since the Riga summit thirty months ago. The European Union is still reeling from Brexit, and from a wave of populism that has swept across the continent threatening decades of painstakingly achieved gains for an open and liberal society.
On Europe's Eastern flank is an increasingly assertive Russia, occasionally belligerent, and these days, rarely friendly.
Caught in the middle, the six Eastern partners have chosen different ways to deal with this reality. Some are closely entangled with Russia - Belarus is part of a Union state with it; Armenia is closely aligned politically, militarily and economically. Azerbaijan has opted for non-alignment, whilst Georgia, Ukraine and Moldova, already connected with the EU through the recently signed association agreements, want even closer integration and have made this their long-term objective.
It is not a black and white situation by any means. Armenia has tried to carve a space for itself, negotiating a new Enhanced partnership agreement with the EU which should be signed imminently. Azerbaijan is negotiating a "strategic partnership" arrangement with the EU, likely to be concluded next year. And even Belarus has been much more open for contacts with the EU in the last two years than before. Regardless of their foreign policy orientation all six countries still have huge challenges in their efforts to modernise, reform and develop.
What began in Riga, will continue in Brussels. The Eastern Partnership will continue to mellow, and its future as a grouping is only symbolic. The EU is going to have to accept that the agendas of the six countries is very different and find ways of dealing with this.
A sense of what is ahead came in the form of a resolution by the European Parliament adopted last week as a recommendation prior to Friday's summit.
It is a wish list. Some issues were lobbied for by some of the Eastern Partners themselves, others reflect the views of groups of MPs. The resolution put emphasis on differentiation, and particularly on the importance that the EU responds to the aspirations of Georgia, Moldova and Ukraine for more integration, leading some time in the distant future to membership - the so-called membership perspective.
This EP resolution whilst only a recommendation can in the future transform into a rallying call.
At the moment no one in the European Commission wants any mention of a membership perspective. That will likely also be the message from the summit. Member states simply have too much on their plate to start considering what after all would be a very ambitious step, and one not without its risks.
Yet not responding at all to the aspirations of the three countries also has huge implications, and in the long-term costs. Within Georgia, Moldova and Ukraine the political debate on the future is ongoing. Realists in the three countries do not expect EU membership anytime soon, but neither are they ready to accept that this should not be possible sometime in the future. Pro Russian elements use the lack of membership perspective as an example of European hypocrisy.
It is true, that the first duty of all concerned is to make the Association Agreements signed in the last years work successfully in order that all sides may reap the benefit from them. Nothing should distract attention from achieving this immediate primary goal.
But with Russia still trying to promote mischief in the region, including through multiple pressures that threaten the very existence and territorial integrity of Georgia, Moldova and Ukraine, the European Union needs to be generous and flexible.
As far as the other three countries are concerned, the summit should offer a clear message that even if from a political distance, the EU is committed to good neighbourly policies, and indeed to working with them to increase prosperity and peace.
Getting the Eastern Neighbourhood right is a key necessity for the future security and prosperity of Europe. The issues should be neither marginalised nor trivialised. The Brussels summit offers an opportunity for important steps on this matter in the right direction - not as an end in themselves but rather as a part of a longer term and more ambitious vision.
The European Union condemned in the strongest possible terms the recent attack in Salisbury. EU leaders agreed with the UK government's assessment that it is highly likely that the Russian Federation is responsible and that there is no plausible alternative explanation.
