German Foreign Minister Guido Westerwelle arrived in Iraq on Saturday for a brief visit - previously unannounced due to security concerns, DPA reported.
Westerwelle is expected to meet with Prime Minister Nuri al- Maliki, president Jalal Talabani, as well as representatives of the Christian minority.
"We want to send a signal of support for political stabilisation of Iraq," he said.
Westerwelle, who heads a business delegation, called on the Iraqi parties to work on the democratic process.
Westerwelle is the first European foreign minister to visit Iraq since the March 7 parliamentary elections.
Last month, al-Maliki was assigned the task of forming a new government to be comprised of groups which spent eight months reaching an agreement on how to allocate the country's leadership positions.
