Lebanese Prime Minister Fouad Siniora is in Syria for talks with President Bashar al-Assad on how to repair strained ties.
Mr. Siniora was met at the border Sunday by his Syrian counterpart Mohammed Naji Otari before heading to Damascus to meet the president.
The visit is the first by a senior Lebanese official since Syria lost its military grip over Beirut. Mr. Siniora's trip comes one day after his government won a vote of confidence in parliament.
The prime minister is in Damascus to discuss improving relations, which soured after Syrian troops pulled out of Lebanon in April, ending a 29-year military presence. Mr. Siniora has said good relations with Syria are crucial to Lebanon's future.
He also is expected to discuss Syria's decision to block Lebanese trucks at the border, which Damascus says is for security reasons.
