US President Donald Trump said no nation should underestimate American resolve, as he arrived in Japan at the start of a marathon Asian tour.
Addressing US troops at Yokota air base near Tokyo, he pledged to ensure the military had the resources needed to keep peace and defend freedom.
Mr Trump's visit comes amid heightened tensions with North Korea over its nuclear programme and missile tests.
It will be the longest tour of Asia by a US president in 25 years.
"No-one, no dictator, no regime... should underestimate American resolve," President Trump told cheering US and Japanese troops shortly after his arrival in Japan.
Before touching down, he told reporters on board Air Force One that he expected to meet Russian President Vladimir Putin during his trip.
"I think it's expected we'll meet with Putin," he said. "We want Putin's help on North Korea."
Mr Trump was meeting Japanese Prime Minister Shinzo Abe for lunch before the two leaders were due to play a round of golf.
Stops in South Korea, China, Vietnam and the Philippines are also on the itinerary in the coming week.
West Ham manager Slaven Bilic says he is under "big pressure" and in a "very difficult" situation after Saturday's 4-1 Premier League defeat by Liverpool.
Thousands of Hammers supporters left London Stadium early for the second home game in a row as the Hammers were left a point above the bottom three.
"The pressure mounts game by game and at this moment it is big," Bilic, 49, told BBC Sport.
"We will see what the club will do. The club is above everyone."
West Ham have lost three of their past four games at London Stadium and were unable to cope with Liverpool's pace on the counter-attack throughout Saturday's game.
Mohamed Salah scored twice for the visitors, with Joel Matip and Alex Oxlade-Chamberlain also on target. Manuel Lanzini briefly gave West Ham home by making it 2-1.
For less than a month’s rent in her hometown of Vancouver, Lydia Lee is having a second storey built onto the villa she rents on the tropical island of Bali.
Relocating to Indonesia seven years ago has meant she’s been able to build her business and afford a much more lavish lifestyle than she could at home. A life coach, Lee can now eat out every day, employ a cleaner and get weekly massages.
She ditched her six-figure salary in marketing and business development and now works for herself and travels the world. But relocating overseas doesn’t always work out so well financially.
Financial shocks
Not all expats find they can afford to live the high-life. InterNations, a networking resource for expats, recently surveyed more than 12,500 people living in 188 countries or territories and the picture the data paint of their finances is remarkably diverse.
