The meeting was set to be held at Moon's presidential office Cheong Wa Dae.
Ngan arrived in Seoul on Tuesday at the invitation from her South Korean counterpart, Moon Hee-sang.
Vietnam is South Korea's largest trading partner in Southeast Asia and fourth largest in the world, with the countries' two-way trade coming to US$63.9 billion last year.
During Moon's visit to Vietnam in March, he and Vietnamese President Tran Dai Quang agreed to boost their bilateral trade to over $100 billion by 2020. (Yonhap)
