The delegation headed by Jean Lambert, who heads the EU Parliament delegation for relations with South Asia, discussed the political developments in the country, the External Affairs Ministry said.
A spokesperson at the EU office in Colombo meanwhile said that that the delegation will visit Trincomalee and Batticaloa this week.
In Colombo they will have discussions with government and opposition politicians including Defence Secretary Gotabaya Rajapaksa and Economic Affairs Minister Basil Rajapaksa, the spokesperson said.
The European Parliamentary delegation visited Sri Lanka last year as well and later submitted a report to the EU parliament regarding its visit.
The report called for constructive and principled engagement between the EU and Sri Lanka despite the disagreements of the past.
EU members had supported a resolution on Sri Lanka at the UN Human Rights Council (UNHRC) in March this year, a resolution which Sri Lanka had objected to.
Sri Lanka told the European Parliament last week the resolution on Sri Lanka at the UN Human Rights Council in Geneva was unnecessary and unwarranted, and could in effect negatively impact the ongoing reconciliation process.
