At Saturday's glitzy gathering in Rio de Janeiro, the 2011 Asian Cup semi-finalists, were drawn alongside Kuwait, the UAE and Lebanon.
With long-haul trips and class opposition standing between his side and a place in the fourth qualifying round, Cho was quick to acknowledge the difficulty of Korea Republic's task.
"We have to play against three West Asian teams. I am afraid of tiredness, time difference, different weather and ground conditions there," he told the Asian Football Confederation's official website.
"They (West Asian teams) will play each other in their region but we have to go there for three matches. How to deal with these three away games will be the question.
"Kuwait are getting stronger. Though, they faltered in the group stage of the AFC Asian Cup, I was impressed with their skills.
"UAE also have good technique and passing skills. We have to be aware of their striker Ismail Matar.
"Lebanon have physical power and strong stamina. It will be different a Lebanon we used to play before," he concluded.
