In international naval defence exercises, the multinational maritime exercise AMAN-19 was hosted by which country as the main organising nation?

Introduction / Context:
Multinational maritime exercises are conducted so that navies from different countries can train together, improve interoperability, and build mutual confidence at sea. AMAN-19 was one such large naval exercise held in 2019, widely covered in defence current affairs. The question checks whether you can correctly recall which country actually hosted AMAN-19, which is important for exams that focus on defence, diplomacy, and international relations.

Given Data / Assumptions:
• The exercise is named AMAN-19 and took place in the year 2019.
• It is described as a multinational maritime exercise, so multiple navies participated.
• The task is to identify the host country among the given options.
• No numerical calculation is required; it is a factual recall question from current affairs and defence awareness.

Concept / Approach:
To answer this question, you need to connect the exercise name AMAN with the country that regularly conducts this series. The AMAN series is a well known multilateral naval exercise hosted by the Pakistan Navy. The event is usually conducted off Karachi, with participation from numerous friendly navies. Recognising this association between the word AMAN and Pakistan allows you to select the correct option confidently and to eliminate other countries that host different exercises under different names.

Step-by-Step Solution:
Step 1: Note the keyword in the question: “multinational maritime exercise AMAN-19”. Step 2: Recall which country conducts the AMAN series of naval exercises. This series is associated with the Pakistan Navy. Step 3: Remember that AMAN-19 was held near Karachi, which is a major port city of Pakistan. Step 4: Compare this recall with the options: Pakistan, Japan, China, India, Sri Lanka. Step 5: Select “Pakistan” as the only option that matches the known host of AMAN-19.

Verification / Alternative check:
You can verify this by recalling that Japan and India usually feature in other named exercises such as Malabar, while China conducts exercises under different names, often with limited partners. Pakistan, on the other hand, regularly advertises AMAN exercises as a symbol of “Together for Peace”, with Karachi as the central venue. Linking AMAN-19 with Pakistan fits this pattern and confirms that Pakistan is the correct host nation for the 2019 edition.

Why Other Options Are Wrong:
Japan: Japan is an important naval power but does not host the AMAN series of exercises, so this is incorrect.
China: China hosts and participates in many exercises, yet AMAN-19 is specifically known as a Pakistan Navy hosted event, so China is not the right answer.
India: India co-hosts and participates in exercises like Malabar and others but not AMAN-19, which belongs to Pakistan, so this option is wrong.
Sri Lanka: Sri Lanka participates in some naval exercises but is not associated as the organiser of AMAN-19, therefore this is also incorrect.

Common Pitfalls:
A common mistake is to confuse AMAN-19 with other multinational naval exercises and to assume that a larger navy, such as that of India or China, must be the host. Another pitfall is guessing based on the perception that Japan or any other developed country conducts most multinational drills. In current affairs based questions, assumptions like these can lead to errors if you do not remember the specific pairing of exercise names and host countries. Focusing on the correct association between AMAN and Pakistan helps avoid such confusion.

Final Answer:
The multinational maritime exercise AMAN-19 was hosted by Pakistan as the main organising country.
