India launched supply chain resilience initiative in April 2021 with _____.

A "supply-chain resilience" initiative is a coalition a few countries form to diversify sourcing of critical goods and cut over-dependence on any single trading partner — it is built among strategically aligned economies with shared trade and security interests, not just any set of a country's trade partners.

India, Japan, and Australia jointly announced the Supply Chain Resilience Initiative (SCRI) on 27 April 2021. Their trade/commerce ministries launched it to build diversified, resilient supply chains across the Indo-Pacific region and reduce dependence on any one country for critical inputs. So the phrase "India launched supply chain resilience initiative in April 2021 with _____" is completed by naming India's other two co-founders of this specific trio.

• Russia and Japan: Russia is not part of this Indo-Pacific trio; India's ties with Russia run through separate defence and energy cooperation channels, not this initiative.

• Australia and Brazil: Brazil is not part of this trio; India's economic engagement with Brazil runs through separate groupings such as BRICS, not this Indo-Pacific framework.

• Brazil and South Africa: neither country is part of this trio; India's ties with both run through the separate BRICS grouping, not this initiative.

The pairing that names the actual two co-founding countries of the SCRI alongside India is the one that correctly completes the sentence.
