Among the BRICS nations, which country was selected to host the 9th BRICS Summit in the year 2017?

Introduction / Context:
This question is based on international groupings and current affairs, specifically the BRICS grouping of emerging economies: Brazil, Russia, India, China and South Africa. Summits rotate among member countries, and questions often ask which country hosted a particular year's summit.

Given Data / Assumptions:

• The summit in question is the 9th BRICS Summit.
• The year is 2017.
• The possible host countries are all BRICS members: Brazil, Russia, India and China.
• We assume the normal rotation and official announcements were followed.

Concept / Approach:
The concept is mainly factual recall of the sequence of BRICS summits. The 8th BRICS Summit was held in Goa, India, in 2016. The next summit, the 9th one, therefore moved to another member, and in 2017 it was hosted by China at Xiamen in Fujian Province. Remembering the locations and hosts of recent summits helps in answering this kind of question quickly.

Step-by-Step Solution:
Step 1: Recall that India hosted the 8th BRICS Summit in 2016 at Goa. Step 2: Recognise that the host of the 9th summit in 2017 was a different member country. Step 3: Recall from news that the 9th BRICS Summit was held in Xiamen, a coastal city in China. Step 4: Match Xiamen with the country China. Step 5: Select China as the correct host country for the 2017 summit.

Verification / Alternative check:
News archives and official BRICS documentation clearly state that the 9th BRICS Summit took place from 3 to 5 September 2017 in Xiamen, China. The theme and declaration issued from Xiamen are widely cited, confirming that China was the host. No such references list Brazil, Russia or India as hosts for the 2017 summit.

Why Other Options Are Wrong:
Brazil: Brazil has hosted earlier BRICS summits but not the one in 2017, which was the 9th summit.

Russia: Russia is a BRICS founding member and has hosted summits in other years, but it was not the host in 2017.

India: India hosted the 8th BRICS Summit in 2016 at Goa, so it did not host the 9th summit immediately the following year.

Common Pitfalls:
Candidates often get confused between consecutive summits, especially India and China hosting in back-to-back years. Another mistake is assuming that since India is often in the news for BRICS, it must have hosted in 2017 as well. Carefully tracking the sequence of summits helps avoid such errors.

Final Answer:
The 9th BRICS Summit in 2017 was hosted by China.
