China celebrated its growing power and confidence with a massive display of military hardware and goose-stepping troops in Beijing on Tuesday, overseen by President Xi Jinping who pledged peaceful development on the 70th birthday of Communist China.<br /><br />The event is the country's most important of the year as China looks to project its assurance in the face of mounting challenges, including nearly four months of anti-government protests in Hong Kong and a economy-sapping trade war with the United States.
