Some observers say the launches may be an attempt by the North to put pressure on Washington to reopen negotiations. The previous seven launches have revealed short-range missile and rocket artillery systems that experts say would potentially expand its capabilities to strike targets throughout South Korea, including USA military bases.
Kim, military leaders and top officials "in the field of national defense science" saw two rounds of test fire Tuesday of "tactical guided weapons including super-large multiple rocket launcher", the official Korean Central News Agency said a day after the launches.
Pompeo continued: "I think President Trump would be very disappointed if Chairman Kim doesn't return to the negotiating table or conducts missile tests that are inconsistent with the agreements that they made when the two of them were together these three times".
"We would be glad to see North Korea and the USA resuming talks on schedule at the end of the month", Wang said.
Trump and Kim Jong-un are due to resume talks later this month as the US looks to usher North Korea into denuclearisation - but the US President's dismissal of Bolton raises concerns regarding this objective. "It set us back".
Pyongyang said on Monday that it was willing to restart nuclear talks with the U.S. in late September but warned that dealings between the sides could end unless Washington takes a fresh approach.

He ended with his mother, Frances Haros, before going into a monologue about Omar's comment on the September 11, 2001 attacks. "We will never forget the thousands of Americans who lost their lives in the largest terror attack on USA soil".
Choe said she hopes the United States will bring "a proposal geared to the interests of the DPRK and the U.S. and based on decision methods acceptable to us".
She warned that "if the US side fingers again the worn-out scenario which has nothing to do with new decision methods at the DPRK-US working negotiation to be held with so much effort, the DPRK-U.S. dealings may come to an end".
"The timing could be convenient for USA diplomacy with North Korea", said Leif-Eric Easley, a professor at Seoul's Ewha University.
State media in North Korea say the country's leader oversaw the test of a "super-large multiple rocket launcher " on Tuesday.
"What remains to be done is running fire test which is most vivid character in terms of the power of multiple rocket launcher", KCNA said.
In April, Kim said he was open to another summit with Trump but set the end of the year as a deadline for the USA to offer improved terms for an agreement to revive the nuclear diplomacy.
Trump has received plaudits and criticisms for his willingness to engage Kim Jong Un directly in three meetings since June a year ago, the first between leaders of two countries that have remained in a technical state of hostilities since the 1950-53 Korean War.
