US military drills with South Korea and Washington's troop presence there are "vital" for regional security, Japan said on Wednesday, raising concerns after US President Donald Trump said the drills would be halted.
"There's three outcomes here: Peace, where we have a win-win solution", Graham said.
The US had previously ruled out suspending military exercises because they have been a big part of its military alliance with South Korea and a deterrent against the north.
Though the Pentagon has claimed all those war games, most of which simulate attacks on North Korea, are "necessary", analysts say they doubt suspending them will have any real impact on United States military capabilities.
Bishop said: "I don't believe that suspension for suspension has actually been agreed".
An end to the "war games" was not in the letter signed by the two men after negotiations ended on Tuesday.
Speaking later, the prime minister struck a noticeably more upbeat tone. "South and North Korea agreed to actively seek the support and cooperation of the worldwide community for the denuclearization of the Korean Peninsula".
In the wake of Trump's unexpected, nearly offhand comments to reporters, the Pentagon had nothing to say about the future of the war games. "They are so poor their people are dying, and their economy is bad". But, you know what? The DPRK's commitment to denuclearize in the Singapore statement is a reaffirmation of its commitment to denuclearize in the Panmunjom Declaration, with all of the conditions attached to it.
All of the concessions KCNA claims Trump made are also things China has said publicly it wants. I'm here one day.
During the 2016 presidential debate, Trump was accused of being a puppet of the Russian president.

"Sanctions are not an end", he said.
She said the global community was at the beginning of a very long process: "The detail is still to be worked through". "A bipartisan (authorization for the use of military force) would really make that letter much more credible". But he added that he hoped to speak to North Korea about the Cold War-era abductions of Japanese citizens by North Korean spies.
The KCNA report, as well as the joint statement after the summit, also mentioned that the president had offered North Korea unspecified security guarantees, which Pyongyang considers an indispensable precondition for nuclear disarmament.
Moon Seong Mook, a former South Korean military official, said Trump's comments on the drills confirmed what many in South Korea had feared all along - that North Korea would attempt to drive a wedge between Washington and Seoul and gain substantial concessions from an unconventional USA president who thinks much less of the traditional alliance than his predecessors.
