TOKYO, May 25 (Reuters) - Market sentiment was a little shaky on Friday with Asian shares on the defensive after U.S. President Donald Trump scrapped a key summit with North Korea, though investors' fears were calmed by Pyongyang's measured response to the cancellation.
North Korean Vice Foreign Minister Kim Kye Gwan said Pyongyang still hoped for a "Trump formula" to resolve the standoff over its nuclear weapons programme, noting that North Korea was open to resolving issues with the United States.
MSCI's broadest index of Asia-Pacific shares outside Japan was almost flat, while South Korea's Kospi pared much of its earlier loss of 0.9 percent. Japan's Nikkei was up 0.1 percent.
On Wall Street the S&P 500 ended 0.2 percent lower on Thursday, though it clawed back a large part of its earlier loss of 0.95 percent.
Even before the reaction from Pyongyang, there were no immediate signs of widespread investor panic with Wall Street's volatility index, seen as a gauge of investors' fears, ending at a four-month low on Thursday.
Analysts said that level of calm reflected investors becoming accustomed to Trump's dramatic negotiation style, in which he makes drastic calls before making compromises, and are increasingly seeing his North Korea's Kim Jong Un adopt a similar approach.
"I suspect they couldn't agree on denuclearisation. But looking at comments from the both sides, none of them is ruling out holding a meeting in the future. So I do not expect to see an immediate escalation in military tension," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui Asset Management.
Adding to political jitters was Trump's raising the spectre of high U.S. tariffs on imported cars, reigniting fears of a trade war, although some investors see this as a Trump tactic to get better deals from big car-exporting countries.
The 10-year U.S. Treasuries yield dipped to as low as 2.955 percent on Thursday as bond prices rose before it ticked back to 2.992 percent in Asia on Friday. It is still off a seven-year high of 3.128 percent hit a week ago.
"For many Asian markets, rises in U.S. bond yields would have been a bigger problem (than cancellation of the meeting between Trump and Kim)," said Yukino Yamada, senior strategist at Daiwa Securities.
Worries that investors could shift assets from emerging markets to higher-yielding U.S. bonds have been a major headwind for emerging markets.
The yen slipped in Asia after hitting a two-week high against the dollar on Thursday in a reflex flight-to-safety reaction to Trump's manouevres.
The dollar traded at 109.60 yen, up 0.3 percent for the day. But it was still off Monday's four-month high of 111.395 yen and looks set to post its first weekly loss in nine weeks.
The yen is seen as a safe haven because of Japan's status as the world's largest net creditor nation.
The dollar extended its losses against the Swiss franc to hit 0.9886 franc overnight, its lowest level since April, before steadying at 0.9921.
The euro traded at $1.1712, slightly above its six-month low of $1.1676 touched on Wednesday, on course to mark its sixth consecutive declining week.
The currency was dogged by worries of a new coalition government in Italy to be formed by two anti-establishment parties, as well as mounting signs of an economic slowdown in the euro zone.
Among emerging market currencies, the Turkish lira tumbled again, giving up a large chunk of the gains it made after the central bank raised interest rates by 300 points on Wednesday.
The lira has been hit by concerns about the central bank's ability to tame double-digit inflation, particularly after President Tayyip Erdogan -- a self-described "enemy of interest rates" -- said he expected to assert more policy control after June 24 elections.
The lira fell 1.5 percent in Asia on Friday.
Oil prices slipped, partly on speculation reduced supplies from Venezuela and Iran could prompt the Organization of the Petroleum Exporting Countries (OPEC) to wind down output cuts in place since the start of 2017.
Russia hinted it may gradually increase output, after having withheld supplies in concert with the OPEC producer cartel since 2017.
OPEC may decide in June to lift output to make up for reduced supply from crisis-hit Venezuela and Iran, which was stung by the U.S. decision to withdraw from a multilateral nuclear arms control deal, OPEC and oil industry sources told Reuters.
Brent crude futures stood at $78.68 a barrel, down 0.15 percent on Friday after a 1.27 percent loss the previous day. U.S. West Texas Intermediate (WTI) crude CLc1 futures were little changed at $70.66 per barrel. They lost 1.57 percent on Thursday.
