JOIN USGuido Westerwelle made the comments after meeting his Chinese counterpart Yang Jiechi in Beijing on an official trip that will be followed by a visit to disaster-struck Japan.
"There can only be a political resolution and we must get the political process underway. That should begin with a ceasefire that Gaddafi must heed to allow the peace process to begin," Westerwelle told reporters.
US, British, French, Canadian, Danish and Belgian jets have attacked Libyan military targets since March 19 under UN Security Council resolution 1973, which authorised "all necessary measures" to protect civilians.
The coalition campaign aims to oust Gaddafi, who is currently fighting an insurgency against his 41-year rule.
China and Germany abstained from the vote on the resolution, which established a no-fly zone over the North African state, and are not participating in the military action against the Libyan strongman's regime.
Yang noted this, saying it showed that "both countries have reservations on different levels."
"We emphasise that Resolution 1973 was conceived as a means of ending the violence and protecting civilians. We are therefore worried by continued reports of deaths and injuries among civilians and continuing clashes," Yang said.
"We hope that the relevant countries will adhere to the resolution and respect Libya's independence and sovereignty. The matter must be dealt with appropriately by diplomatic and political means."
