Germany’s new Ambassador-Designate to the Republic of South Africa, Oliver Rentschler, has arrived in Johannesburg to take up his new diplomatic assignment, beginning a new chapter in the longstanding relationship between Germany and South Africa.

Rentschler was welcomed upon his arrival by Martin Slabber, Director for Western Europe at the Department of International Relations and Cooperation (DIRCO). Slabber shared the news of the Ambassador-Designate’s arrival, welcoming him to South Africa and highlighting his extensive experience within Germany’s Federal Foreign Office.

Rentschler takes up his new position at a significant time in bilateral relations, with South Africa and Germany continuing to deepen cooperation in trade, investment, energy, climate action, technology and the just energy transition.

Who is Oliver Rentschler?

Oliver Rentschler is a veteran German diplomat with extensive experience in German foreign policy, European affairs, economic diplomacy and international cooperation.

He holds a Master’s degree in Political Economy from the University of Bayreuth, which he completed between 1991 and 1995. His diplomatic career began with assignments that included Germany’s missions in Kuwait and Iraq, followed by postings and professional engagements involving Albania, Slovenia, Burkina Faso, Ethiopia and Ireland.

Rentschler entered Germany’s higher foreign service in 1996. His subsequent career has included significant responsibilities in European and international diplomacy. Between 2001 and 2003, he served as Deputy Head of Mission at the German Embassy in Conakry, with responsibility for Guinea and Sierra Leone. He later worked with the European Commission and Germany’s Permanent Representation to the European Union in Brussels.

His experience also extends to the highest levels of European foreign-policy coordination. Rentschler served in the private offices of German Foreign Ministers Frank-Walter Steinmeier and Guido Westerwelle, before moving to the European External Action Service (EEAS).

From 2012 to 2014, he served as Deputy Head of Cabinet to Catherine Ashton, then the EU High Representative for Foreign Affairs and Security Policy and Vice-President of the European Commission. He subsequently served as Deputy Head of Cabinet to Federica Mogherini, Ashton’s successor, from 2014 to 2019.

Rentschler later held senior positions within the EEAS, including responsibility for interinstitutional relations, policy coordination and strategic communication.

Senior Experience in Climate Diplomacy and Geoeconomics

Before his appointment to South Africa, Rentschler served in a senior leadership role at Germany’s Federal Foreign Office, where he was Director-General for Climate Diplomacy and Geoeconomics.

His responsibilities placed him at the intersection of foreign policy, international economic relations, climate diplomacy and strategic economic interests.

His work has included engagement on issues such as climate security, energy transition, economic cooperation and geoeconomics. In 2024, for example, he participated in international discussions on the links between climate change, peace and security.

His professional background is particularly relevant to South Africa, where cooperation with Germany includes major areas such as energy transition, climate policy, sustainable development and economic cooperation.

Germany has identified South Africa as an important partner in Africa, with bilateral diplomatic relations dating back to 1951.

Welcomed by DIRCO’s Martin Slabber

Upon arriving in Johannesburg, Rentschler was welcomed by Martin Slabber, Director for Western Europe at DIRCO.

Slabber has extensive experience in South Africa’s diplomatic engagement with European countries. His professional responsibilities have included work involving Germany and German-speaking countries, and he previously served as South Africa’s Ambassador to the Philippines.

Slabber’s reception of the incoming German Ambassador-Designate represents an early official engagement as Rentschler begins his assignment in South Africa.

The welcome also comes within the established diplomatic framework through which DIRCO manages South Africa’s bilateral relations with European partners.

Next Step: Copies of Letters of Credence

Rentschler’s arrival in South Africa is followed by the formal accreditation process required for a newly appointed head of mission.

The next step will be the presentation of copies of his Letters of Credence to South Africa’s Chief of State Protocol at DIRCO.

The presentation of the copies forms part of the formal diplomatic process preceding the Ambassador’s presentation of his original credentials to the Head of State.

Following this stage, Rentschler will await the opportunity to present his original Letters of Credence to President Cyril Ramaphosa.

The presentation of the original Letters of Credence to the President will formally complete his accreditation as Germany’s Ambassador to the Republic of South Africa.

Until that formal ceremony takes place, he is appropriately referred to as Ambassador-Designate.

A Strategic Moment for Germany-South Africa Relations

Rentschler arrives in South Africa as Pretoria and Berlin continue to build on a broad strategic partnership.

The relationship encompasses trade and investment, energy, climate cooperation, technology, sustainable development and the just energy transition.

South Africa is Germany’s important economic and political partner on the African continent, while Germany remains an important European partner for South Africa.

Rentschler’s background in geoeconomics and climate diplomacy could be particularly significant as both countries seek to expand cooperation around economic transformation, energy security, renewable energy and the transition towards low-carbon economies.

His extensive experience in European diplomacy also gives him a strong understanding of multilateral engagement, international partnerships and the complex relationship between economic interests and foreign policy.

Beginning a New Diplomatic Chapter

The arrival of Oliver Rentschler in Johannesburg marks the beginning of his diplomatic mission in South Africa and comes at an important stage in the development of Germany-South Africa relations.

With decades of experience spanning German diplomacy, European foreign policy, climate diplomacy, economic affairs and geoeconomics, Rentschler brings considerable international experience to his new assignment.

His forthcoming engagement with DIRCO’s Chief of State Protocol, followed by the presentation of his Letters of Credence to President Ramaphosa, will mark the next stages of his formal accreditation.

As he begins his tenure, Rentschler is expected to engage with the South African Government, diplomatic community, business sector and wider stakeholders as Germany and South Africa continue working to strengthen their longstanding partnership.
