The NITI Aayog released its inaugural quarterly report, Trade Watch, which evaluates India’s trade and commerce scenario.

NITI Aayog Observations

  • India’s Limited Success: The report acknowledges India’s limited success in leveraging the China Plus One strategy, as compared to Vietnam, Thailand, Cambodia, and Malaysia.
    • These countries have emerged as significant beneficiaries due to competitive advantages like cheaper labor, simplified tax structures, lower tariffs, and proactive free trade agreements (FTAs).
    • India has not fully captured the opportunities presented by the global shift away from China-centric supply chains.
    • Multinational companies are de-risking their operations by diversifying to other countries.
  • Global Trade Disruptions: US-China trade conflicts, including recent reciprocal trade restrictions, have fragmented global supply chains.
    • Export bans on critical materials and increased tariffs on Chinese goods are reshaping trade dynamics.
  • Sectoral Challenges: Indian iron and steel exports have seen a steep decline (33% in Q1 FY25) due to weak domestic demand and oversupply from China.
    • India’s iron and steel industry is particularly vulnerable to the EU’s Carbon Border Adjustment Mechanism (CBAM), which could impose 20–35% tariffs.
  • Opportunities in US Trade Policies: Tariffs on Chinese goods (up to 60%) could provide India a competitive edge in global markets.
    • Trade diversification offers opportunities in underrepresented sectors where India’s global share is below 1%.

Background of Israeli Occupation

UN resolution

  • The Israeli occupation began after the Six-Day War of 1967, where Israel captured several territories, including the West Bank, Gaza Strip, East Jerusalem, and the Golan Heights.
  • These territories have since been at the heart of the Israel-Palestine conflict, with demands for a Palestinian state and Israel’s withdrawal remaining unresolved.
  • The Israeli settlement construction in these territories has been widely criticized as a violation of international law, including the Fourth Geneva Convention which protects civilians during wartime, ensuring humane treatment and basic rights.
  • Two-State Solution Framework: A two-state solution envisions Israel and Palestine coexisting peacefully as independent states within the borders established before 1967.
    • The international community largely supports this framework as the basis for lasting peace in the region.
  • Resolution on Syrian Golan Heights: The resolution demanded that Israel withdraw from the Syrian Golan Heights to the pre-June 1967 line, in accordance with relevant Security Council directives.
    • It declared Israel’s 1981 decision to impose its laws, jurisdiction, and administration on the Golan Heights as null and void.

India’s Arguments for Voting Decisions

  • Support for Palestine and Syrian Golan Resolutions
    • India reaffirmed its longstanding support for a two-state solution as the basis for peace between Israel and Palestine.
    • India emphasized the need for adherence to international law, including the cessation of settlement activities and the recognition of Palestinians’ right to self-determination.

Nano Bubble Technology

Context: Recently, the Ministry of Environment, Forest and Climate Change launched ‘Nano Bubble Technology’ for cleaning and purifying water of National Zoological Park, Delhi to promote the health of aquatic animals.

About Nano bubble technology

  • Nano bubble technology is a method of using tiny bubbles to improve water quality.
  • Nanobubbles are ultra-fine bubbles (less than 200 nanometers in diameter) that are nearly invisible to the eye. 
  • Nanobubbles can be generated using a variety of methods, including centrifugal force, ultrasound, Electrolysis etc. 
  • How It Works:
    • Suspension and Stability: Nanobubbles are stable due to their small size and high surface energy, allowing them to stay suspended in the water for long durations.
    • Surface Charge: They possess a strong negative charge, attracting and breaking down impurities like algae, organic waste, oil, and grease.
    • Oxygen Enrichment: Nanobubbles increase the dissolved oxygen levels in water. This enhanced oxygenation promotes the breakdown of organic matter and improves water quality.
    • Oxidative Effects: Upon collapsing, nanobubbles generate hydroxyl radicals, which are powerful oxidizing agents capable of degrading pollutants and killing pathogens.
  • Advantages: 
    • They can remove pollutants like algae, organic waste, oil, and grease. 
    • Nanobubbles are also more energy-efficient than traditional methods and are chemical-free, making them environmentally friendly.

Other applications

  • Plant growth: Can improve oxygen delivery to plant roots, which can increase nutrient uptake and enhance plant growth. 
  • Drug delivery: Used to deliver drugs and are functionalized with biocompatible surfaces. 
  • Medical imaging: Used as imaging agents due to the echogenic properties of their gas core. 
  • Anaerobic digestion: Improve the anaerobic digestion process by reducing sulfide and volatile fatty acid levels. 
  • Textile industry: The Indian Institute of Technology, Ropar developed an air nano-bubble technology that can reduce water use in the textile sector by up to 90%.
