UNSC Resolution 1172: 5 Key Milestones in India-China Ties
UNSC Resolution 1172 (1998)
The article notes the contribution of the role of former Prime Minister Atal Bihari Vajpayee to the development of the international relations between India and China. He recalls his 1979 trip to China as India’s External Affairs Minister, becoming the first senior Indian leader to visit the country after the 1962 India-China war, and the development of bilateral relationships, the tensions between the countries following India’s championship on nuclear tests in 1998, and the peace-building processes involving dialogue and agreements.
This is within the backdrop of recent India-China tensions along the Line of Actual Control (LAC) and as such, a discussion of historical landmarks, such as UNSC Resolution 1172 and intricate set of controversies between the two countries is pertinent.

About UNSC Resolution 1172 (1998):
- Date adopted: 6 June 1998.
- In May 1998, India carried out the Pokhran-II nuclear tests, while Pakistan conducted the Chagai-I tests.
- The international community was alarmed, fearing a nuclear arms race in South Asia.
- Resolution 1172 was co-sponsored by China and the United States and passed unanimously.
Key Provisions:
- Both India and Pakistan condemn their nuclear tests.
- Issued a call to India and Pakistan to halt additional nuclear testing and not to arm their nuclear weapon arsenals.
- This has caused the two countries to share a pressurization urge to accept the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and don the Nuclear Non-Proliferation Treaty (NPT) as the states that do not possess nuclear weapons.
- Necessary caution and open communication to reduce regional tensions.
- Requested each of the states not to aid India or Pakistan on their nuclear weapons development.
India’s stand:
- India rejected the resolution, labeling it discriminatory, and conducted nuclear tests, citing national security concerns, particularly in light of China’s nuclear capabilities and Pakistan’s close ties with China.
