Zlatko Lagumdžija (born 26 December 1955) is a Bosnian diplomat and politician serving as Permanent Representative of Bosnia and Herzegovina to the United Nations since July 2023.

Lagumdžija began his political career during the Bosnian War as deputy Prime Minister of the Republic of Bosnia and Herzegovina, advising then-president Alija Izetbegović.

The SDP BiH-led government facilitated the passage of the Election Law, a prerequisite to Bosnia and Herzegovina's accession to the Council of Europe.

Lagumdžija earned his high school diploma as a part of the Youth For Understanding[2] exchange student program in Allen Park, Michigan in 1973.

[3] At the end of the Bosnian War, Lagumdžija helped to secure funds from the Soros Foundation with which to rebuild the Group Support System facility at the University of Sarajevo.

The strategic objective of the Management and Information Technologies Center, which housed the GSS facility, was to "assist and promote the transition of Bosnia and Herzegovina to a democratic, market-driven economy.

[citation needed] Lagumdžija began his political career during the Bosnian War as deputy prime minister, advising then-president Alija Izetbegović.

After protracted negotiations, disagreements and delays, he signed the Agreement on Succession Issues of the Former Socialist Federal Republic of Yugoslavia on behalf of Bosnia and Herzegovina.

"[9] The SDP BiH-led government facilitated the passage of the Election Law, which was not only an important step towards democracy, but also a prerequisite to Bosnia's accession to the Council of Europe.

The European Union and the Office of the High Representative repeatedly attempted negotiations to appease the Bosniak–Bosnian and Serb–Croat divided political blocs, in parallel to the Bosnian constitutional crisis, all ending in failure.

A round of talks between party leaders was held in Mostar on 5 September 2011, hosted by Croat politicians Božo Ljubić and Dragan Čović, with Milorad Dodik, Mladen Bosić, Sulejman Tihić and Lagumdžija in attendance.

On the same day, an EU spokesperson warned that the country risked losing funding through the Instrument for Pre-Accession Assistance if the political situation did not stabilize.

[19] As “credible efforts” towards the implementation of the Sejdić–Finci ruling remained the outstanding condition for the entry into force of the Stabilisation and Association Agreement, in June 2012, Czech Commissioner Štefan Füle launched a High Level Dialogue on the Accession Process (HLAD) with Bosnia and Herzegovina, tackling both the Sejdić–Finci issue and the need for a coordination mechanism for the country to speak with a single voice in the accession process.

[20] In February 2013, the European Commission decided to step up its involvement, with the direct facilitation of talks by Füle, in coordination with the Council of Europe's secretary-general Thorbjørn Jagland.

[21] In March and April 2013, with the support of the Director-General for Enlargement Stefano Sannino, the EU Delegation in Sarajevo facilitated a series of direct talks between party leaders, with no concrete outcome.

However, Washington came out with a request for their extradition because "the U.S. still believes they are a threat to American interests and that the US Government refused to publicly disclose evidence to the court in Bosnia and Herzegovina because it would endanger its methods of intelligence-gathering."

[23] In 2009, an investigation by the Cantonal prosecution of Sarajevo against Lagumdžija, the ex-Federal Minister of Interior Tomislav Limov and others involved was launched but later dropped.

"[25] The court dismissed the accusations, Lagumdžija eventually sued Dnevni avaz for libel and the newspaper was ordered to pay him 10,000 BAM in damages.
