Kuwait and Lebanon Sunday signed here a cooperation protocol on attracting bilateral investment in a latest measure to boost economic ties between the two countries. The protocol came after a meeting between visiting Lebanese Prime Minister Saad Al-Hariri and Kuwaiti Prime Minister Sheikh Nasser Al-Mohammad Al-Ahmad Al-Jaber Al-Sabah. A report from the official KUNA news agency said the two countries also inked a memorandum of understanding for industrial cooperation and exhibitions. Details of the protocol or memorandum were not available in KUNA's report. Al-Hariri arrived here Saturday for a two-day official visit to the Gulf Arab emirate, which has maintained strong relations with Lebanon. During the visit, Al-Hariri met Kuwait's Amir Sheikh Sabah Al- Ahmad Al-Jaber Al-Sabah and other high-ranking officials, with both sides pledged to boost bilateral relations in various fields. The oil-rich Gulf emirate has contributed 300 million U.S. dollars in financial aid to Lebanon's reconstruction in the wake of the country's conflicts with neighboring Israel in 2006, KUNA said in February.
