Some ethical considerations in global friendships include respecting cultural differences, avoiding stereotypes or assumptions, maintaining confidentiality, and being mindful of power dynamics. It's important to approach global friendships with cultural sensitivity and awareness, recognizing and respecting differences in norms, values, and communication styles. Avoid making assumptions or stereotypes based on your friend's culture or background, and strive to learn and understand their individual experiences and perspectives. Respect your friend's privacy and confidentiality, and be mindful of power dynamics, especially in cross-cultural contexts where one party may hold more privilege or influence than the other.
