BEIJING, May 25 (Reuters) - Almost all base metals rose on Friday, led by Shanghai nickel which hit a near three-year high, after the dollar took a hit following U.S. President Donald Trump's decision to cancel a summit with North Korean leader Kim Jong Un. A weaker dollar makes metals more expensive for holders of other currencies and can support prices. FUNDAMENTALS
* LME COPPER: Three-month copper on the London Metal Exchange was up 0.2 percent at $6,894 tonne, as of 0225 GMT, building on a 0.2 gain in the previous session.
