A reception held by the SCO at its Beijing headquarters highlighting the entry of India and Pakistan turned out to be an embarrassment for the organisers as India's Red Fort with the tricolour was shown as Lahore's Shalimar Gardens in a Pakistani tableau.
Chinese Foreign Minister Wang Yi, Indian envoy to China Vijay Gokhale along with the ambassadors of Pakistan Masood Khalid and other Shanghai Cooperation Organisation (SCO) members attended the function.
Both Indian and Pakistani diplomats pointed out the faux pas to the organisers.
India and Pakistan were admitted as members into the six-member grouping at the Astana Summit last week.
The group is now comprised of China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Uzbekistan, India and Pakistan.
Afghanistan, Belarus, Iran and Mongolia have an observer status in the grouping that is increasingly seen as a counterweight to NATO.
