SEOUL, June 17 (Xinhua) --South Korea and the United States are expected to announce the suspension of "large-scale" military drills this week, with the provision that they would restart if the Democratic People's Republic of Korea (DPRK) failed to keep its promise to denuclearize, Yonhap said on Sunday.

Citing an unnamed South Korean government source, the South Korean news agency said the suspension was likely to affect only major joint exercises, not more routine military training.

"The South Korean and US military authorities have been having close consultations over the combined exercises that US President Donald Trump has said he will stop," a source said on condition of anonymity.

"This week, the South Korean and US defense ministries will jointly announce the results of their discussions," the source added.

US President Donald Trump surprised officials in Seoul and Washington when he pledged to end "war games" after his summit with DPRK leader Kim Jong Un in Singapore last week.

The source also noted that Trump's mention of "war games" might involve large-scale annual maneuvers, such as the springtime Key Resolve and Foal Eagle exercises, and the summertime Ulchi Freedom Guardian.
