Climate change, migration and energy issues were at the heart of talks between Hungarian President Janos Ader and Zuzana Caputova, his Slovakian counterpart, in Budapest on Thursday. At the talks in the presidential Sandor Palace, Ader underlined that the world "is in the eleventh hour" in acting on climate change. Ader said the preservation of water bases was "at least as important" as climate protection. The president said he was paying close attention to the recent implementation of a law in Slovakia that grants constitutional protection to the country's water bases. The two leaders agreed that the use of nuclear energy was indispensable in achieving climate protection goals and that every country should have the right to shape their own energy policies. As regards migration, Ader and Caputova were in agreement that Europe's external borders must be protected and that it would be wrong to implement mandatory migrant quotas.
