James Soong's comments came after he told reporters in the Vietnamese city of Danang at the weekend that he had good exchanges with both US President Donald Trump and Secretary of State Rex Tillerson, during informal moments between summit events.
"We don't want to create trouble in the Taiwan Strait, and lead the US, China and Japan, and all observers, to think we are a troublemaker. The whole world doesn't hope for Taiwan to be a troublemaker," Soong said.
"We hope to use peaceful means to solve relevant problems."
Soong also said he had a "natural interaction" with Chinese President Xi Jinping.
Relations between Beijing and Taipei have nosedived since President Tsai Ing- wen was elected last year.
