India faces several challenges and hurdles in its international affairs. Some of these challenges include:

• Neighbouring countries: India shares its borders with several countries, including China and Pakistan, with whom India has had a tense relationship due to border disputes and cross-border terrorism.
• Terrorism: India has been a victim of terrorism for several years. It has faced challenges in convincing the international community to take action against countries that harbor terrorists.
• Trade agreements: India has struggled to negotiate favorable trade agreements with other countries, which has negatively impacted its economy.
• Climate change: India, as a developing nation, is facing the challenges of tackling climate change while trying to maintain its economic growth.
• Multilateral organizations: India is often sidelined in multilateral organizations like the UN Security Council, which limits its participation in global decision-making processes.

These challenges and hurdles have a significant impact on Civil Services aspirants, as they need to be well-prepared to deal with these issues. They need to have in-depth knowledge and understanding of international relations and diplomacy to represent India on the global stage.
