SHANGHAI/TOKYO, May 16 (Reuters) - Asian stock markets dipped on Wednesday after Pyongyang abruptly called off talks with Seoul, throwing a U.S.-North Korean summit into doubt, while surging bond yields revived worries about faster U.S. interest rate hikes that could curb global demand.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was down 0.2 percent as Pyongyang's move appeared to mark a break in months of warming ties between North and South Korea and with Washington. cancellation of the June 12 summit in Singapore could see tensions on the Korean peninsula flare again even as investors worry about China-U.S. trade tensions and the sustainability of global economic growth.
"This will weigh on the Korean reconstruction beneficiaries that have had a strong run on peace and even reunification hopes recently," JPMorgan (NYSE:JPM) analysts wrote in a note.
"The broader risk for the region if talks do break down is that Trump no longer feels the need to keep China on side and could escalate trade tensions again."
Strong U.S. retail sales and factory data on Tuesday pushed the U.S. 10-year yield through a key level to hit 3.095 percent, its highest since July 2011, raising worries about higher borrowing costs for companies worldwide.
The 10-year yield US10Y=RR was last at 3.063 percent.
The rise in yields hurt U.S. share markets on concerns it would undercut stock valuations. .N

CURRENCIES
The strong U.S. data underpinned the dollar in currency markets.
The US dollar index .DXY , which tracks the greenback against a basket of six major rivals, hits a 2018 high of 93.46 on Tuesday and last stood at 93.31.
The euro fell to as low as $1.18155 EUR= , its lowest level in about five months.
The dollar held firm at 110.27 yen after having hit a near four-month high of 110.45 yen JPY= on Tuesday.
The yen largely shrugged off data that showed Japan's economy shrank by 0.6 percent on an annualised basis in the January-March quarter, a sharper contraction than the median estimate of 0.2 percent and marking the end to eight straight quarters of expansion.
"U.S. retail data assured that the world is still in a synchronised global growth. If U.S. retail had been a disappointment, the market would have taken Japan's GDP more negatively," said Tohru Yamamoto, chief fixed income strategist at Daiwa Securities.
High-yielding Asian currencies were particularly vulnerable to higher U.S. yields, which could prompt investors to shift funds out of emerging markets.
