Chinese Ambassador was summoned for the dressing down from Global Affairs Canada officials on Thursday after the Pentagon revealed the presence of the balloon over the sensitive military sites in the western US.

Iran PressAmerica: Canada announced that it had called China's ambassador onto the carpet -- but otherwise remained tight-lipped -- as Ottawa and Washington expressed their disapproval about a high-altitude surveillance balloon found floating over the United States.

US officials also announced Secretary of State Antony Blinken was postponing a planned high-stakes weekend diplomatic trip to China, even as the Biden administration weighed a broader response to the discovery of the balloon.

On Friday, Pentagon spokesman Brig.-Gen. Patrick Ryder described the object as a manoeuvrable surveillance balloon flying at an altitude of about 60,000 feet, or 18,288 metres, with a "payload" or basket underneath. 219
