The Gwadar port is a part of:

Correct answer: Belt and Road Initiative. Gwadar is the flagship port of CPEC, which is part of China’s Belt and Road Initiative.

Background: CPEC was launched in 2015.

• ECO corridor: ECO is a regional economic cooperation organization, not a corridor containing Gwadar.
• CASA-1000: CASA-1000 is an electricity transmission project.
• TAPI: TAPI is a gas pipeline project.

Did you know? Gwadar is a deep-sea port on the Arabian Sea in Balochistan.

Memory trick: Gwadar → CPEC → BRI.
