RIYADH - US President Donald Trump said on Sunday Washington's relations with Bahrain were set to improve, after meeting with the king of the Gulf Arab state during a visit to Saudi Arabia. 'Our countries have a wonderful relationship together but there has been a little strain but there won't be strain with this administration,' Trump said during photo session with Sheikh Hamad bin Issa al-Khalifa in Riyadh. 'We're going to have a very, very long-term relationship. I look forward to it very much - many of the same things common.'
