What can the world expect from King Charles III?

Following the death of his mother, Elizabeth II, Charles has ascended to the British throne after more than 70 years as the heir apparent.
In a statement released shortly after the official announcement of her passing, Charles described the death of his "beloved" mother as "a moment of the greatest sadness for me and all members of my family." The coming days will be a time during which Charles both assumes his new duties and mourns a great personal loss.
