Oman's Sultan Haitham bin Tariq al-Said congratulated Democrat Joe Biden on winning the US Presidential election, the state news agency reported on Saturday.
Haitham bin Tariq sent a letter to Biden expressing "his sincere congratulations for winning the confidence of the American people and for his election as President of the upcoming presidential term", the state news agency added.
A centrist who promises to bring calm to Washington after four turbulent years under President Donald Trump, Biden is the oldest man to win the presidency -- a position he twice sought unsuccessfully during his long political career, before being elected vice president to Barack Obama in 2008.
Overall turnout on Tuesday broke records with some 160 million people pouring out across the United States after a deeply polarizing campaign complicated by the resurgent Covid-19 pandemic.
