2020 was the year of the new coronavirus. The year when killings of black men and women by the police sparked protests in the U.S. and around the world.
The year of a fiercely fought U.S. Presidential election with an outgoing president reluctant to accept the result.
A year with a promising start to U.S.-China ties but then it took a turn for the worse. 2020 was a year like no other.
