South Korea and the United States on Saturday kicked off a joint naval exercise in the Sea of Japan involving three US aircraft carriers amid heightened tensions on the Korean Peninsula.
The soldier crossed to South Korea from the North Korean side of the heavily guarded Joint Security Area (JSA) to Freedom House in the South, according to the JCS.
Yonhap News Agency said the soldier sustained gunshot wounds to the elbow and shoulder and was transported to hospital by a helicopter of the United Nations Command, which oversees the armistice on the Korean Peninsula.
Panmunjom, located inside the four-kilometre-wide Demilitarised Zone that separates the two Koreas, is where an armistice was signed to pause the 1950-53 Korean War, with North Korea and China on one side and the American-led UN Command on the other.
"President Moon and President Xi may have discussed ways to improve the countries' overall relations, while the meeting with Premier Li will likely focus on details of ways to do so", an official from the South Korean presidential office Cheong Wa Dae said earlier.
Also to be mobilized are 11 U.S. Aegis ships and seven South Korean warships.
Meanwhile, North Korea's foreign ministry spokesperson, on Saturday, said in Pyongyang that Trump's current trip to "our surrounding region" is a warmonger's visit for confrontation to rid the DPRK of its self defensive nuclear deterrence. The Aegis technology refers to missile tracking and guidance.
Trump has recently reiterated a sharp warning to North Korea during his speech in South Korea's parliament saying, "Do not underestimate us".
In recent months, North Korea has tested intercontinental ballistic missiles and conducted it's most powerful nuclear test. Pyongyang also flew two missiles over Japan.
It has repeatedly threatened to launch ballistic missiles into the waters around the USA territory of Guam.
