Germany plans to send 1,200 military personnel to Lebanon as part of the proposed international peacekeeping force, according to a German magazine.
Der Spiegel reported on Monday that the German navy would send frigates and speedboats to oversee the Lebanese coast.
The air force may also contribute Tornado reconnaissance jets to prevent weapons smuggling by the Lebanese militant group Hezbollah, according to the magazine.
Berlin reportedly awaits a formal request from the Lebanese government.
European Union nations pledging to send ground troops to Lebanon include Italy with 3,000 troops, France (2,000) Spain (1,200), Poland (500), Belgium (400) and Finland (250).
Turkey, China, Nepal and New Zealand are also to take part in the 15,000-strong mission.
