US Secretary of State Marco Rubio, on a three-day India visit, defended his planned trip to Reliance Industries' Jamnagar refinery, saying engaging companies with large refining capacity is vital for global energy security. 'Energy is related to national security,' Rubio said, adding that refining capability is as critical as crude oil production amid global supply disruptions.
