On June 24th, the EU Commission published new per diem rates on their website, see https://ec.europa.eu/europeaid/work/procedures/implementation/per_diems/index_en.htm_en.
Again, the EU has had to take account of general price developments and has increased rates in some cases. In the Arab world in particular, the increased security situation had an impact on the Per Diems.
All new rates have already been updated on the country pages of www.per-diems.info .
