During an hour of talks with Prime Minister Ehud Olmert, Annan said he pressed for a lifting of the embargo, imposed after the start of the war against Lebanons Hizbollah guerrilla group on July 12, mainly on economic grounds.
At a news conference after their meeting, Olmert rebuffed Annan, saying any relaxation of pressure on Lebanons ports and airspace depended on the full implementation of U.N. resolution 1701, which governs the ceasefire with Hizbollah.
The (resolution) is a fixed buffet and everything will be implemented, including the lifting of the blockade, as part of the entire implementation of the different articles, he said.
Olmert was equally firm when it came to suggestions from Annan that Israel should withdraw all its troops from southern Lebanon within days or weeks, once up to 5,000 U.N.-backed peacekeepers are on the ground.
Israel will pull out of Lebanon once the resolution is implemented, Olmert said, indicating a longer timeline.
In the talks, Olmert also reiterated his call for the U.N. force to be deployed not just in southern Lebanon but along the border with Syria, a deployment that the U.N. resolution makes dependent on a request from the Lebanese government.
Annan, in Jerusalem after visiting Lebanon, is trying to strengthen a shaky, two-week-old truce that ended a 34-day war between Israel and Hizbollah. His top priority had been the lifting of the blockade, a request made by Lebanons government.
It is important not only because of the economic effect it is having on the country but it is also important to strengthen the democratic government of Lebanon with which Israel has repeatedly said it had no problems, Annan said.
The secretary-general said he hoped to double to 5,000 the number of U.N. troops in Lebanon soon and urged Israel and Hizbollah to end swiftly disputes blocking a lasting ceasefire.On Tuesday, Israeli Defense Minister Amir Peretz said Israel would pull out thousands of troops once a reasonable number of U.N. soldiers had been deployed, but did not give a figure.
Resolution 1701 calls for a deployment of 15,000 U.N. peacekeepers by November 4, alongside Lebanese army forces.
In a sign that Annan had made little progress in his discussions with Israeli leaders, he did not take questions from journalists after meeting Foreign Minister Tzipi Livni and neither was forthcoming about their hour-long talks.
Annan restricted himself to saying he hoped resolution 1701 could be the basis for a durable peace. Aides said he would travel to Syria and Iran, Hizbollahs backers, later this week.
Annan said the Lebanese saw the blockade as a humiliation and infringement of their sovereignty. But he also urged Beirut to exert control over its borders to stop arms smuggling.On a visit to southern Lebanon on Tuesday, Annan said serious irritants to the truce were also the fate of abducted Israeli soldiers and that of Lebanese prisoners held in Israel.
