Trump says N. Korea problem 'will be solved'

In the presence of Japanese Prime Minister Shinzo Abe, the issue of North Korea's growing nuclear and ballistic missile threats is also likely to be high on the agenda. It's a world problem.

Bishop said the "loud and clear" message from Haley was that "when the United States said all options are on the table, they mean it, they are not kidding", pointing to the USA sending a nuclear submarine to the region.

"It will be solved", he said before going into closed-door talks with Abe, without giving further details.

Tensions between Pyongyang and Washington over North Korea's continued missile programme have escalated since Trump took office in January.

That's according to a White House readout of the pair's meeting today ahead of the G-7 summit of wealthy nations.

It has carried out two atomic tests since the beginning of a year ago, insisting it needs nuclear weapons to defend itself against the threat of invasion.

"We'll be discussing terrorism but I think there will really be a particular focus on the North Korea problem - it's a big problem it's a world problem".

The US is anxious that if Kim is not stopped, other countries in the region including Japan and South Korea would be compelled to seek their own nuclear capability as a defence measure.

U.S. Secretary of State Rex Tillerson recently told a United Nations gathering that the U.S. would not hesitate to sanction other countries that support the North's illegal activities.

More encouragingly, the North's main trade partner and ally China appeared to be getting onside with the global community, she added in a separate interview with radio station 2GB.

North Korea's grain imports from China showed a more than fivefold surge last month from a year ago, a USA broadcaster said Friday.

This was despite Trump's comments earlier this month that he would be "honored" to meet North Korean leader Kim Jong Un "under the right circumstances". The leaders met in Sicily, where they released a joint declaration stating that Pyongyang must immediately and fully comply with all relevant UN Security Council Resolutions and abandon all nuclear and ballistic missile programs in a complete, verifiable and irreversible manner.
