It also said this was Gandhi's first foreign visit since his elevation as party chief in December.
Gandhi's visit is part of his interactions with Persons of Indian Origin (PIOs). Gulf countries have the biggest Indian diaspora of more than 35 lakh.
Gandhi will be chief guest at the three-day valedictory function organised by 'Global Organisation of People of Indian Origin' (GOPIO) starting on Monday.
Delegates from 50 countries are participating in the event.
Gandhi will also have an interactive session with business leaders of Indian Origin.
Gandhi's outreach is being seen as a move to popularise Congress among the large Indian diaspora.
