(Adds Belgian prime minister)

SALZBURG, Austria, Sept 20 (Reuters) - European Union leaders met in Salzburg, Austria, for an informal summit to discuss migration and Brexit. Below are comments of leaders arriving on Thursday.

BELGIAN PRIME MINISTER CHARLES MICHEL

ON BREXIT

"Today I can see that it is necessary to make all the steps because the proposals are not enough in order to have an agreement."

EUROPEAN COMMISSION PRESIDENT JEAN-CLAUDE JUNCKER

ON THE PRESENTATION OF BRITISH PM THERESA MAY ON WEDNESDAY

"It was interesting, it was polite, it was not aggressive. She is doing her job."

LUXEMBOURG PRIME MINISTER XAVIER BETTEL

ON BREXIT

"We listened to Teresa May yesterday, I think that she told us the efforts the British government did, and today we listen to Michel Barnier on the different points. I still believe that there's some difficult points. I fully believe that we will be able to find an agreement."

"It's a compromise from both sides, it's not on one side."

AUSTRIAN CHANCELLOR SEBASTIAN KURZ

On Brexit

"You know that, as before, the approaches are very different. But to report something positive, inside the room, away from the hard media statements outside, I think both sides are aware that they will only reach a solution if they move towards each other."
