In recent years, tremendous artefacts have been shown at museums in other countries. Personally, I disagree to bring it back, and supports will illustrated in the following paragraphs.
First and foremost, many historical objects must be prevented from brakedown. Several artsfacts are builded at a long-lasting time and several categories need highly be careful such as pottery, textile, and others. When they need to tranportation for bring it back to their origin that have a high risk to fagile which lead to loss their vulues; even both country will have a plan to prevent and best-packing.
For instance, many ancient objects of Eygip are brakedown when they try to brought it back from other countries. Therefore, the best option of historical objects perhaps it need to preserve in other countries more than origin regional.
in addtion to preseve artefacts, It will solve the risk of conflic and encourage relationship between countries. Tremendous artefacts had brought to other countries for a long time and it is unable to specify who was the owner-leading to conflic between courntries if they want to bring it. However, If both region commit to preventing and sharing their identity together, it will improve their relationship and enhance cooperation in the other parts. For instance, both regions can cooperate in the part of businesses of travel to encourage their citizens which travel in each regions and explore culture between them. As a result, it can be avoid some conflic and improve their ralationship.
As I mentioned, there are tremendous boons of not bringing artefacts to origin country. Especially, prevent fagile of historical objects and encourage relationships between countries.
