Why foreign dignitaries wear red when meeting Xi Jinping

Xiomara Castro, the president of Honduras, had laid the groundwork for a successful visit to Beijing this month. In March her country ditched ties with Taiwan in favour of China. Honduras is also in the process of joining the Shanghai-based New Development Bank, a World Bank knock-off co-founded by China. But perhaps Ms Castro felt something extra was needed. When she met her counterpart, Xi Jinping, she wore a red trouser suit and shirt with a flowing red neck tie (pictured).
