US President\u00a0Donald Trump\u00a0and Saudi Crown Prince\u00a0Mohammed bin Salman\u00a0have discussed military deals, investment in the US, and security cooperation, during the prince's first visit to the White House.\r\nReferring to the political shake-up that Saudi Arabia has witnessed in recent months, Trump on Tuesday praised the 32-year-old crown prince, popularly known as MBS, in his new role.\r\n"[...] the relationship, now, is probably as good as it's really ever been, and I think will probably only get better. Tremendous investments made in our country. And that means jobs for our workers, jobs for our people," Trump said in a press briefing after the meeting.\u00a0\r\nTrump held up charts to show the depth of Saudi purchases of US military hardware, ranging from ships to missile defence to planes and fighting vehicles.\r\n"Saudi Arabia is a very wealthy nation, and they're going to give the United States some of that wealth, hopefully in the form of jobs, in the form of the purchase of the finest military equipment anywhere in the world," he said.\r\nFor his part, MBS, who is 39 years younger than Trump, pointed to the history of the alliance between the two countries.\r\n"We are the oldest ally of America from the Middle East," he said, "with more than 80 years of alliance and big interests - politically, economically, security. The foundation of the relation[ship] is really huge and deep."\r\nLast year, the two leaders agreed on a plan for $200bn worth of Saudi investments with the US, including large purchases of US military equipment.\r\nHowever, in Tuesday's meeting, Bin Salman said the plan exceeded expectations, doubling the number of investments between Saudi Arabi and the US.\u00a0\r\n"And, as you know, Mr President, from day one you've reached this office, we've planned to tackle $200bn for opportunities in the next four years, but it end up with $400bn for opportunities," MBS said.\u00a0\r\nMeeting a 'tragicomedy'\r\nMarwan Bishara, Al Jazeera's senior political analyst,\u00a0said the reception in the Oval Room was a "tragicomedy".\r\n"On the political level, the American president is trying to sell the crown prince to the American public, when Saudi Arabia's image is really bad," he said.\r\n"Certainly the crown prince is coming in to pay up at least in part his commitments to the United States in terms of commercial deals and buying arms."\r\nBut at a more strategic level, he said, the visit has more to do with realigning\u00a0Saudi Arabia\u00a0and the\u00a0US\u00a0against\u00a0Iran.\r\nGulf crisis in focus\r\nTrump\u00a0was expected to urge\u00a0MBS\u00a0to find a solution to the\u00a0Gulf crisis with Qatar\u00a0during the\u00a0White House\u00a0visit, according to a senior White House official.\u00a0\r\nThe official, speaking on condition of anonymity, said Trump still hoped to hold a summit with Arab Gulf leaders in May.\r\nSaudi Arabia, the\u00a0UAE,\u00a0Bahrain\u00a0and\u00a0Egypt\u00a0cut diplomatic and trade ties with Qatar\u00a0on June 5, 2017, accusing it of\u00a0supporting "terrorism".\r\nQatar\u00a0rejected the allegations as "baseless".\r\n\r\nThe US has repeatedly called on the countries to engage in dialogue.\r\nMBS's visit is the first by an Arab Gulf leader in a series of bilateral meetings that Trump is scheduled to have over the next couple of months.\r\nMBS will be in the US for about two weeks, meeting politicians and business leaders on a trip\u00a0designed to "rehabilitate" the kingdom's image\u00a0in the country, analysts say.\r\nLast month, Sheikh Mohammed bin Abdulrahman Al Thani, Qatari foreign minister,\u00a0said that his country would be willing to participate in a\u00a0US-GCC summit\u00a0next spring, provided that the blockading countries' motivation is based on real will and not coercion.\r\nAsked about the summit at a briefing in Washington, DC on Monday, Adel al-Jubeir,\u00a0Saudi foreign minister,\u00a0said he was unaware of any specific plans for a summit.\r\n"Qatar is irrelevant," he said.\u00a0\r\nThe last US-GCC summit was held in May 2017 in the Saudi capital Riyadh, just before the crisis unfolded.\r\nTrump and MBS would also discuss Iran,\u00a0Russia\u00a0and possible investments in US companies, among other issues, the White House official said on Monday.
