US President Donald Trump "fully supports" Dutch, Australian and other nations working together to bring the people responsible for shooting down Malaysia Airlines Flight 17 to justice.
The president offered his support during a meeting with Dutch Prime Minister Mark Rutte at the White House on Thursday.
All 298 people, including 38 Australian citizens and residents, aboard MH17 died when the plane was struck by a missile over Ukraine in 2014.
"The two leaders also noted that yesterday marked the five-year anniversary of Malaysia Airlines Flight MH-17 being shot down," the White House read-out of the leaders' meeting stated.
"The United States fully supports the ongoing work of Dutch authorities and the Joint Investigation Team to bring justice to those responsible."
Dutch prosecutors last month charged Russians Igor Girkin, Sergey Dubinsky and Oleg Pulatov and Ukrainian Leonie Kharachenko with the mass killing.
The JIT comprises officials from the Dutch Public Prosecution Service, Dutch police and criminal justice authorities from Australia, Belgium, Malaysia and Ukraine.
All four charged were officials in the pro-Russian Donetsk People's Republic fighting for independence from Ukraine and, if not captured or handed over by Russia, likely will be prosecuted in absentia under Dutch law in The Hague next year.
Donetsk Defence Minister Girkin, Intelligence Head Dubinsky, Deputy Intelligence Head Pulatov and field commander Kharachenko were allegedly responsible for the Buk missile launcher used to shoot down MH17 being brought into the area from Russia.
