Consider the following countries :
1. Australia
2. Canada
3. China
4. India
5. Japan
6. USA
Which of the above are among the 'free-trade partners' of ASEAN ?

Correct Option: (c) 1, 3, 4 and 5

ASEAN has entered into free trade agreements (FTAs) with several dialogue partners, collectively known as ASEAN Plus One agreements. Among the options, ASEAN has established FTAs with Australia, China, India, and Japan. Canada and the USA are not among ASEAN's free-trade partners (they are dialogue partners but do not have a direct ASEAN-wide FTA). Thus, items 1, 3, 4, and 5 are correct.
