I have enough facts. Writing the note now.

CINBAX-II 2026: India–Cambodia Bilateral Military Exercise

CINBAX = Cambodia–India Bilateral Exercise; an Indian Army–Royal Cambodian Army joint exercise on Counter-Terrorism (CT) under Chapter VII of the UN Charter [S1][S2].
CINBAX-II (2026) marks the transition from a Table Top exercise (2024) to a field-level company-strength joint exercise in Cambodia [S1][S2].
UPSC relevance: India's Act East policy, defence diplomacy with ASEAN, expanding bilateral exercise grid.

Indian Army contingent departed on 03 May 2026 for the second edition of CINBAX, to be held 04–17 May 2026 at Camp Basil, Kampong Speu Province, Cambodia [S1].

1st edition (CINBAX-I): Joint Table Top Exercise held at Foreign Training Node, Pune, 01–08 December 2024; 20 personnel from each side, drawn from an Infantry Brigade [S2].
Themes of CINBAX-I: Joint Training Task Force for ISR (Intelligence, Surveillance, Reconnaissance), information & cyber warfare, hybrid warfare, HADR, logistics/casualty management [S2].
First-ever visit of a Cambodian Army Chief (Lt Gen Hun Manet) to India: 2–4 Feb 2023 — laid groundwork for institutionalised defence ties [S3].
Defence Cooperation MoU between India and Cambodia is one of seven bilateral agreements covering credit lines, water resources, oil & gas, etc. [S3].

Exercise name: CINBAX-II 2026 [S1].
Edition: 2nd; first field exercise (1st was Table Top) [S1][S2].
Dates: 04–17 May 2026 [S1].
Venue: Techo Sen Phnom Thom Mreas Prov Royal Cambodian Air Force Training Centre (Camp Basil), Kampong Speu Province, Cambodia [S1].
Indian contingent: 120 personnel, majorly from a Battalion of the Maratha Light Infantry Regiment [S1].
Cambodian contingent: 160 personnel, Royal Cambodian Army [S1].
Scope: Company-level joint training for sub-conventional operations [S1].
Legal framework: Chapter VII of the UN Charter (action with respect to threats to peace, breaches of peace, acts of aggression) [S1][S2].
Implementing ministry: Ministry of Defence, Government of India [S1].

Geopolitical / Strategic
Reinforces Act East Policy & Indo-Pacific outreach; Cambodia is an ASEAN member often seen as China-leaning, making defence access strategically valuable [S3].
Mirrors India's growing exercise basket with ASEAN states (VINBAX with Vietnam, MAITREE with Thailand) [S4].
Operationalises the Defence Cooperation MoU signed in the bilateral agreements list [S3].
Legal / Constitutional
Conducted under UN Chapter VII template — aligns training with UN Peacekeeping norms, where both states are contributors [S1].
Administrative / Military
Indian side led by Maratha Light Infantry, one of the oldest infantry regiments — signals prestige assignment [S1].
Foreign Training Node, Pune acts as standing venue for Indian Army's bilateral table-top exercises [S2].
Historical
India's earliest substantive defence outreach to Cambodia matured only post-2022; first Cambodian Army Chief visit to India in Feb 2023 is the inflection point [S3].

Dec 2024: CINBAX-I Table Top Exercise, Pune [S2].
Jul 2024 – Jul 2025: 1st India–Cambodia Year of Tourism observed [S3].
Mar 2025: 3rd India–Cambodia Foreign Office Consultations at Siem Reap [S3].
03 May 2026: Indian contingent departure for CINBAX-II [S1].

CINBAX is between India and Cambodia (not Vietnam – VINBAX) [S1][S4].
1st edition: Pune, Dec 2024, Table Top format [S2].
2nd edition venue: Camp Basil, Kampong Speu Province, Cambodia [S1].
Indian contingent strength in CINBAX-II: 120; Cambodian: 160 [S1].
Indian unit: Maratha Light Infantry Regiment [S1].
Framework: Chapter VII of UN Charter [S1].
Level of training: Company-level, sub-conventional ops [S1].
Cambodian counterpart force: Royal Cambodian Army; venue is a Royal Cambodian Air Force training centre [S1].
VINBAX (Vietnam) and MAITREE (Thailand) are sibling ASEAN exercises [S4].
First Cambodian Army Chief visit to India: Lt Gen Hun Manet, Feb 2023 [S3].

GS-II: India and its neighbourhood / bilateral & regional groupings — India-ASEAN, Act East Policy.
GS-III: Security — defence cooperation, counter-terrorism, UN peacekeeping.
Possible stems: 1. "Joint military exercises have become the principal currency of India's Act East defence diplomacy." Discuss with reference to recent India–ASEAN exercises. 2. "Examine the strategic significance of deepening India-Cambodia defence ties in the context of Indo-Pacific balancing." 3. "How does training under Chapter VII of the UN Charter enhance India's peacekeeping credentials?"

Confusing CINBAX (Cambodia) with VINBAX (Vietnam) — both Chapter VII themed.
Assuming CINBAX-II is in India — it is in Cambodia (Kampong Speu) [S1].
Calling the venue an Army base — it is a Royal Cambodian Air Force training centre [S1].
Treating CINBAX-I as a field exercise — it was a Table Top [S2].
Mis-attributing the Indian unit (it is Maratha LI, not Maratha Regiment / Mahar Regiment) [S1].
