Convincing European governments to invest in Indonesian infrastructure has likely been at the top of President Joko Widodo's mind as he tours the region this week, but his counterparts may have a more pressing concern.
"The worry, of course, is terrorism," said Colin Chapman, founder and editor-in-chief at think-tank Australian and ASEAN Strategies.
Europe is aware of the potential Southeast Asia's largest economy offers in terms of increased foreign direct investment and trade but counterterrorism could overshadow discussions Widodo holds in Germany, England, Belgium, and the Netherlands, Chapman said.
The 54-year old leader, commonly known as Jokowi, is in Europe from April 18-22, and met with German President Joachim Gauck on Wednesday.
From Paris to San Bernardino to Brussels, a string of global terror attacks in recent months have shaken governments, fueling a renewed focus on intelligence sharing as a terror prevention tool. Europe, especially, is on high alert due to the huge influx of refugees and migrants entering its borders from war-torn regions including Syria and Iraq.
Indonesia, home to the world's largest Muslim population, is no stranger to extremist violence and foreign companies operating in the country have long factored security into their decisions. National police recently stepped up a crackdown on extremists following bomb attacks and shootings in Jakarta in January.
Richard Graham, a U.K. MP as well as trade envoy to Indonesia, said the two nations shared a strong interest in counter-terrorism.
