June 24 (Reuters) - Hong Kong stocks ended roughly flat on Monday as investors pinned their hopes for any signs of thaw in Sino-U.S. trade negotiations at the G20 summit later this week.
** The Hang Seng index rose 0.1%, to 28,513.00 points, while the China Enterprises Index gained 0.3%, to 10,952.94 points.
** Investors are nervously awaiting an expected meeting between U.S. President Donald Trump and Chinese President Xi Jinping later this week for any signs of a de-escalation in a trade war that is damaging the global economy and souring business confidence. The leaders will meet on the sidelines of the G20 summit in Japan.
** China and the United States should be willing to make compromises in trade talks and not insist only on what each side wants, Chinese Vice Commerce Minister Wang Shouwen said on Monday.
** U.S. Vice President Mike Pence on Friday decided to call off a planned China speech, which also increased optimism ahead of trade talks. Pence had upset China with a fierce speech in October in which he laid out a litany of complaints ranging from state surveillance to human-rights abuses.
** Still, most analysts doubt the two sides will come to any meaningful agreement as the tensions have extended beyond tariffs, particularly after Washington put Huawei, the world's biggest telecoms gear maker, on a blacklist that effectively bans U.S. firms from doing business with the company.
** Around the region, MSCI's Asia ex-Japan stock index was firmer by 0.19%, while Japan's Nikkei index closed up 0.13%.

** The three biggest H-shares percentage decliners were China Communications Construction Co Ltd, which was down 1.34%, China Telecom Corp Ltd, which fell 1.3%, and China Merchants Bank Co Ltd, down by 1.2%.
** At close, China's A-shares were trading at a premium of 27.40% over Hong Kong-listed H-shares. (Reporting by the Shanghai Newsroom; Editing by Subhranshu Sahu)
