NOT a characteristic of Gross National Happiness (GNH) that Bhutan is implementing: Rapid economic expansion
Explanation: Gross National Happiness (GNH) is a development philosophy and guiding principle in Bhutan, which emphasizes holistic well-being and happiness of its citizens rather than solely focusing on economic growth. Bhutan's approach to development is centered around four pillars: sustainable development, preservation of natural resources, promotion of cultural values, and good governance. Rapid economic expansion, although it may lead to increased material wealth, is not the primary focus of GNH in Bhutan. Instead, Bhutan aims to achieve balanced and sustainable development that prioritizes the well-being of its people and the environment.
