However, the error was quickly caught by an Indian diplomat who drew the minister's attention towards it and Krishna switched to his own speech.
Foreign ministry officials say the confusion was created because the Portuguese minister decided to speak extempore, and a copy of his speech was handed out to all foreign ministers.
Speaking at the UNSC at a debate on security and development on Friday, Krishna read out the wrong speech for about three minutes before being corrected by India's envoy to the UN Hardeep Singh Puri.
The Portuguese minister had already spoken before India. Krishna is here on a two-day visit to push India's agenda for Security Council reforms.
