* Will sign statement committing to fossil fuel cuts
* Response to Trump's pull-out of U.S. from Paris pact
* Lingering EU complaints over investor access to China

BRUSSELS, June 2 (Reuters) - China and the European Union pledged unity in fighting global warming on Friday, a day after President Donald Trump announced a U.S. withdrawal from the Paris climate pact, but showed lingering divisions on international trade.
A meeting between Chinese Premier Li Keqiang and top EU officials will end with a joint statement, backed by all 28 EU states, committing the European Union and China to full implementation of the 2015 Paris Climate Agreement.
The joint statement, the first between the China and the EU, will commit to cutting back on fossil fuels, developing more green technology and helping raise $100 billion a year by 2020 to help poorer countries cut their emissions.
China has emerged as Europe's unlikely partner in areas from free trade to security, and the talks in Brussels will also address North Korea's missile tests and global steel overcapacity.
Trump's announcment on Thursday that he would take the United States out of the Paris deal, saying it would undermine the U.S. economy and cost jobs, drew anger and condemnation from world leaders and heads of industry.
The European Commission, the EU executive, described the U.S. pullout from the pact to fight the dangers of global warming and signed by more than 190 countries, as a sad day for the global community, but said it would seek new alliances.
Commission President Jean-Claude Juncker told a business conference on Friday that China and the EU recognised the need for international solutions and this was nowhere more important than full implementation of the Paris agreement.
"There is no reverse gear to energy transition. There is no backsliding on the Paris Agreement," Juncker told the conference before a meeting with Li and European Council chief Donald Tusk.
While China needs EU technical know-how to reduce the pollution blighting its cities, the EU is looking to Beijing to take action against emissions blamed for increased droughts, rising seas and other affects of climate change.
China overtook the United States as the world's biggest emitter of greenhouse gases in 2007.
A broader final communique will be issued focusing on a range of other issues expected to be raised at the talks, including a commitment to free trade and measures needed to reduce a global steel glut.
On these topics, however, China and the EU seemed less united.
Juncker referred to a World Bank report placing China 78th of 190 countries in terms of the ease of doing business.
"A big economic powerhouse needs to be higher than mid-table," he said, adding that a planned EU-Chinese investment treaty needed to be completed to ensure reciprocal relations.
France, Germany and Italy have mooted the idea of allowing the EU to block Chinese investment in Europe, partly because European companies are denied similar access in China and because of risks of China acquiring prized European technology.
Juncker also referring to "worrying overcapacity" in certain sectors, notably Chinese steel, and urged Beijing to allow European companies access to contracts for China's multi-billion dollar Belt and Road infrastructure investment initiative.
In reply, Li said China was working hard to promote a trade balance with Chinese tourism to Europe now far greater than EU tourism in China. Foreign investment opportunities, he said, were far different from when China first opened up.
"I do hope you can put things into context. We find the problems, but we are working on them...Our ranking is getting better," he said. (Reporting by Philip Blenkinsop; Editing by Mark Heinrich)
