"We are willing to work with all parties concerned to achieve denuclearisation and safeguard peace and stability on the Korean Peninsula," Lu Kang told a daily press briefing while responding to Pence's comments in Seoul.
"Just in the past two weeks, the world witnessed the strength and resolve of our new president in actions taken in Syria and Afghanistan," Pence told media referring to missile strikes in Syria for deadly chemical attack and Mother Of All Bombs dropped on an ISIS tunnel complex in Afghanistan.
"North Korea would do well not to test his resolve or the strength of the armed forces of the United States in this region," Pence said.
Lu said the situation in the Korean Peninsula was highly sensitive, complicated and high risk and all sides should avoid taking provocative actions that add fuel to fire.
Asked about US National Security Adviser H R McMaster's comments that North Korea should stop destabilising behaviour and stop developing nuclear weapons, Lu said "We have taken note of the remarks."
China has put forward a "dual-track approach" and a "suspension for suspension" proposal to ease tensions on the peninsula and create conditions for peace talks, he said.
