“[The visit] comes at a time when relations between Ireland and France have never been better,” Mr Martin said ahead of his departure.
“We will also, of course, discuss the big challenges facing Europe and the wider world [including] energy, the slowing economic outlook, and the immoral war Russia is waging on Ukraine.
“As winter approaches, and as Russia continues its relentless attacks on vital civilian infrastructure, Ukraine’s citizens are facing into a very difficult winter without heat and electricity. I will be discussing with President Macron how the EU can continue to provide the humanitarian support Ukraine will need.”
On Friday, Mr Martin will attend a signing ceremony for the Celtic Inter-Connector - a project linking electricity grids in Ireland and France – which will also be attended by Minister for Environment Eamon Ryan and the French minister for energy transition Agnès Pannier-Runacher.
The Taoiseach will address a business breakfast at the Irish Embassy on Friday morning which will focus on energy cooperation between the two countries.
