The 32-year-old de facto Saudi leader, named crown prince last year, is doing the rounds of world capitals as he ushers in sweeping reforms to liberalise his conservative kingdom and moves to stamp its regional supremacy.
Here is a recap of his trip so far.
Red carpet in Cairo
The prince starts out on March 4 in Cairo where he is welcomed by President Abdel Fattah al-Sisi at the international airport, a red carpet rolled out at the foot of his plane.
The following day the two countries agree on a joint $10-billion fund to develop the Egyptian side of a $500-billion futurist mega-city that is planned to straddle Egypt, Saudi Arabia and Jordan.
Called NEOM, which means "new future" in a combination of English and Arabic abbreviations, it will be a biotech and digital hub spread over 26,500 square kilometres (10,000 square miles).
A royal welcome in London
On March 7, Britain rolls out its own red carpet for the crown prince but his three-day visit is controversial, drawing protests over Saudi Arabia's role at the head of a military coalition operating in war-ravaged and destitute Yemen.
Prince Mohammed lunches with Queen Elizabeth II at Buckingham Palace and goes on for talks with Prime Minister Theresa May on the kingdom's reforms, trade and investment relations, and defence and security cooperation.
Around 200 anti-war protestors line up outside Downing Street as the crown prince meets May, who has to defend the visit in parliament.
Great friends with Trump
On March 20, US President Donald Trump gives the prince an effusive welcome at the White House, hailing a "great friendship".
"The relationship is probably the strongest it's ever been -- we understand each other," says Trump as the young leader embarks on a nearly three-week tour of the United States.
"Saudi Arabia is a very wealthy nation and they are 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," Trump says.
On March 23, the United States formally approves defence contracts totalling more than $1 billion with Saudi Arabia.
On April 2, in an interview published in US news magazine The Atlantic, Prince Mohammed says that Israelis, as well as Palestinians, "have the right to have their own land".
The remark suggests increasing rapprochement with Israel, with whom Saudi Arabia has no formal diplomatic relations but is firmly allied with the United States.
