RAMALLAH, July 17 (Xinhua) -- Palestinian President Mahmoud Abbas on Wednesday said that he refuses any escalation as a path to resolve issues related to Palestinian refugees in Lebanon, urging for a dialogue.

Abbas's comments came in the opening of the Palestine Liberation Organization (PLO) executive committee meeting earlier in Ramallah city.

"There are a number of issues that require an immediate dialogue with the brothers in Lebanon, because we want to settle those issues through dialogue and negotiations, and we reject escalation from any party," he said.

Abbas added that Azzam Al-Ahmad, PLO's member on charge of Lebanese affairs, will be dispatched to Beirut "to follow up on those issues."

Lebanese official policy denies Palestinian ownership in Lebanon.

Palestinian refugees, most of whom are Lebanese-born, face difficult requirements to own and officially register a commercial enterprise at local authorities.

They are required to deposit a large sum of money and to employ 75 percent of Lebanese workers in their enterprise.

In 2010, Lebanon passed a law that grants Palestinians to work legally in menial jobs in the private sector.

Palestinian refugees in Lebanon, estimated at over 500,000, are still unable to work in the public sector or in professions such as medicine, law or engineering, where membership of Lebanese syndicates is compulsory.
