In February 2014, Röttgen accompanied German President Joachim Gauck on a state visit to India – where they met with Prime Minister Manmohan Singh and Sonia Gandhi, among others – and Myanmar. Shortly after the referendum on the status of Crimea held on 16 March 2014, he and his counterparts of the Weimar Triangle parliaments – Elisabeth Guigou of France and Grzegorz Schetyna of Poland – visited Kyiv to express their countries' firm support of the territorial integrity and the European integration of Ukraine. This was the first time that parliamentarians of the Weimar Triangle had ever made a joint trip to a third country.
