WASHINGTON, Sept. 4 (Xinhua) -- The White House said on Monday that U.S. President Donald Trump had talked with South Korean and German leaders over phone on the Korean Peninsula nuclear issue.

The White House said Trump and South Korean President Moon Jae-in agreed to use "all means at their disposal" to maximize pressure on the Democratic People's Republic of Korea (DPRK).

Trump and Moon underscored the grave threat that the DPRK's latest provocation poses to the entire world, said the White House in a statement.

"They also pledged to strengthen joint military capabilities," said the statement, adding that Trump gave his in-principle approval to South Korea's initiative to lift restrictions on their missile payload capabilities.

Trump also provided his conceptual approval for the purchase of billions of dollars' worth of military weapons and equipment from the United States by South Korea, the statement added.

In a related development, Trump and German Chancellor Angela Merkel discussed the Korean Peninsula nuclear issue in a phone call and both reaffirmed the importance of "close coordination at the United Nations."

A White House statement said both leaders condemned "continued reckless and dangerous behavior" by the DPRK and Trump noted that the "latest provocation only serves to increase the international community's resolve to counter" the DPRK's nuclear program.

The statement also said that all options to address the DPRK nuclear issue are on the table.

Meanwhile, China's permanent representative to the United Nations Liu Jieyi on Monday condemned the latest nuclear test by the DPRK and urged the country to return to the track of dialogue. China will not allow chaos and war on the Korean Peninsula, he said.

Liu said the suspension-for-suspension proposal and dual-track approach put forward by China together with the Russian proposal of a step-by-step approach is a realistic and feasible roadmap for the settlement of the issue, asking the relevant parties for due consideration and positive responses.

The DPRK on Sunday detonated a hydrogen bomb that can be carried by an intercontinental ballistic missile, DPRK's Central Television announced.

DPRK's nuclear testing and launches using ballistic missile technology violate UN Security Council resolutions.
