The test looked to be of a 600mm calibre multiple-launch rocket system that North Korea first introduced last month, said adjunct senior fellow Ankit Panda at the Federation of American Scientists.
Choe's statement was apparently aimed at pressuring the United States to make concessions when the North Korea-U.S. talks restart.
North Korea is widely believed to want the United States to provide security guarantees and extensive relief from US-led sanctions in return for limited denuclearization steps.
Trump's efforts to engage with North Korea almost fell apart altogether in February after he followed Bolton's advice at a second summit in Hanoi and handed Kim a piece of paper that called for the transfer of Pyongyang's nuclear weapons and bomb fuel to the United States. "I hope we've left in good standing, maybe we have and maybe we haven't". "In the meantime, we have our hostages back, we're getting the remains of our great heroes back and we've had no nuclear testing for a long time".
The launch was the eighth by North Korea since US President Donald Trump and North Korean leader Kim Jong-un met in June at the heavily militarized border between the two Koreas.
Choe said she hopes the United States will bring "a proposal geared to the interests of the DPRK and the USA and based on decision methods acceptable to us". And he's using that to make a deal with North Korea? "Whether it actually does or whether Bolton's view was more deeply entrenched in USA thinking on this matter is yet to be seen".
KCNA also released photos of the test that showed a smiling Mr Kim, who has been on hand for nearly all of his state's series of missiles and weapon tests that started in May, standing by a launcher.
It was a huge embarrassment for the young North Korean leader, who made a dayslong train trip to the Vietnamese capital to obtain the sanctions relief he needs to revitalize his country's troubled economy.
Trump and Kim agreed then to restart working-level negotiations for denuclearization talks that have been stalled since an unsuccessful second summit between Trump and Kim in Hanoi in February.
Analysts tell Reuters that North Korea carries out weapons tests for many reasons, including reassurance for its own defense establishment.
Kim "gave field guidance" for Tuesday's test, the Korean Central News Agency reported. This suggests North Korea is trying to maintain the momentum for dialogue with the United States, experts say. South Korea's top nuclear envoy was due to go to China, the main benefactor of Kim's government, this week to discuss developments on the divided peninsula.
