Angela Merkel and Emmanuel Macron will sign a new Franco-German treaty - hoping to breathe new life into half a century of political partnership.
The Aachen treaty calls for closer work - in defence and the economy, as well as cultural integration, however it has been met with dismay from politicians on both sides of the border.
Labelled as 'high treason' by one French MEP and labelled as a 'Macron-money grab' by Alexander Gauland from the AfD - the agreement is supposedly designed to inspire greater unity in a fracturing Europe.
The treaty calls for cabinet meetings between politicians from both countries at least four times a year as well as coordinated defence projects. it also stipulates French support for Germany sharing its seat at the UN Security Council.
Refugee policy appears not to have been specifically addressed, however.
It’s nearly 60 years since the first Joint Declaration of Franco-German friendship was signed by Konrad Adenauer and Charles de Gaulle.
