Explanation:

The first statement is correct. The Global Compact for Safe, Orderly and Regular Migration is indeed the first-ever UN global agreement on a common approach to international migration in all its dimensions. It was adopted by an overwhelming majority of United Nations member states in 2018 and represents a significant effort to improve cooperation and governance on migration issues.

The second statement is incorrect. The Global Compact for Migration does not aim to stop inter-country migration; instead, it seeks to improve the management of migration, address challenges associated with today’s migration, and strengthen the contribution of migrants and migration to sustainable development. It is not about solving issues in conflict countries to stop migration but rather about managing migration effectively and humanely.

The third statement is incorrect. Austria, Hungary, and the Czech Republic are among several countries that have expressed reservations about the pact or decided not to sign the Global Compact for Migration. These countries have various concerns about the agreement, particularly regarding how it might impact national sovereignty and the management of their borders.

Therefore, only the first statement is correct.
