The drills, which have been staged in August every year, consist of the Ulchi defensive command post exercise staged by the South Korean government and the Freedom Guardian computerized command and control training by South Korean and USA troops.
The South Korean defense ministry said in a statement: "South Korea and the United States have agreed to suspend all planning activities regarding the Freedom Guardian military drill scheduled for August".
"Consistent with President Trump's commitment and in concert with our Republic of Korea ally, the United States military has suspended all planning for this August's defensive "wargame" (Freedom Guardian)", White said.
"We are still coordinating additional actions". A Pentagon spokesman said the United States had refrained from any decision on two sets of war games played every winter and early spring, Key Resolve and Foal Eagle.
US and South Korean officials confirmed Tuesday the suspension of scheduled joint military drills, making good on a pledge by President Donald Trump during his summit with North Korea's leader.
Both South Korea and the US have said a peace treaty is possible only if North Korea agrees to give up its nuclear arsenal.
At his summit with U.S. President Donald Trump last week in Singapore, Kim pledged to work toward denuclearization in exchange for U.S. security guarantees. They then were held in April.
Cancellation of Ulchi Freedom Guardian was inevitable after Trump assured Kim Jong-un, in their summit in Singapore that the United States would call off war games while Kim gave assurances of "complete denuclearization". "No decision has been made yet with regard to other [joint military] exercises", the authorities said.
The unification ministry said Tuesday it had endorsed the request from the group devoted to commemorating the first-ever inter-Korean summit June 15, 2000. The annual UFG exercise is participated by government administrative agencies, major private mobilization entities, advanced army, naval, and air forces, Marine Corps, U.S. forces in S. Korea, war-supporting U.S. forces' capability.
Those are bigger concessions that are unlikely to be granted by the USA without concrete steps by North Korea toward denuclearization.
Speaking to reporters in Singapore, Trump said that pausing the drills would save the U.S. "a tremendous amount of money" and described them as "very provocative" - echoing North Korea's criticism that the exercises are a rehearsal for a US-led invasion.
"To me, the idea of this as a cost saving measure doesn't really make much sense", Denmark said. The Hill reports the USA and South Korea conduct three major exercises and some other smaller ones a year.
Xi said he was pleased to see North Korea's decision to promote economic reforms, adding that China's own reform and opening up process had meant the Chinese people's eyes had been open to the world.
Last week, Russian energy major Gazprom announced it resumed talks with Seoul over the construction of a gas pipeline connecting Russia with North and South Korea.
During last year's exercises, Pyongyang fired an intermediate-range missile over Japan in what its state media described as a "muscle-flexing" countermeasure to the drills.
