BEIJING - U.S. President Donald Trump arrived in Beijing on Wednesday evening for what he calls a "very exciting" summit with Chinese President Xi Jinping, with the rest of the world closely watching to see whether any significant developments regarding the Iran war or Taiwan emerge from their discussions.

Trump is joined by more than a dozen top executives from major American companies. He is hoping to clinch huge business deals between the world's two most powerful countries, despite long-running trade friction and an intense race to gain an edge in emerging technologies.
