The nation’s defense intelligence chief says he’s wary of North Korea’s claim that it’s ready to negotiate on its nuclear program and will halt tests.

The South Korean government has announced North Korea agreed to stop testing nuclear weapons and missiles if it holds talks with the U.S. on denuclearization. The two Koreas also agreed to hold summit talks in late April.

Lt. Gen. Robert Ashley, director of the Defense Intelligence Agency, told the Senate Armed Services Committee on Tuesday that he doesn’t share some lawmakers’ optimism about the latest development.

Ashley said: “We’ll have to see how this plays out.”

President Donald Trump is citing “possible progress” in talks with North Korea, but says it may also be “false hope.”

Nonetheless, Trump adds that a “serious effort” is being made by all sides.

Trump commented Tuesday on Twitter after the South Korean government announced that North Korea has agreed to halt tests of nuclear weapons and missiles if it holds talks with the U.S. on denuclearization. South Korea and North Korea have also agreed to hold summit talks in late April.

Trump tweeted: “Possible progress being made in talks with North Korea. For the first time in many years, a serious effort is being made by all parties concerned. The World is watching and waiting! May be false hope, but the U.S. is ready to go hard in either direction!
