(Adds analyst comment, detail; updates prices) MELBOURNE, July 26 (Reuters) - London copper climbed to its highest in more than two years on Wednesday, buoyed by a weaker dollar and talk that China's appetite for refined metal could grow if it curbs scrap imports. Expectations that China could look at banning some imports of copper scrap from the end of 2018 fueled the rally in copper prices, said analyst Dan Morgan of UBS in Sydney. "If true, it could make a reasonable impact short-term," he said. "These moves would make sense in the context of reforms going on in China, with moves to reduce pollution." China notified the World Trade Organization (WTO) last week that it would stop accepting shipments of rubbish such as waste plastic and paper as part of a campaign against "foreign garbage."

* TECHNICAL ANALYSIS: Traders said technical momentum was stoked when copper broke long-standing resistance through $6,000-$6,050 and as copper prices adjust to a weaker dollar. "Fundamentals are fine, but not so vigorous as to fuel such a rally," said a source at a Chinese smelter.
