Transnationalism in the context of "Nation states"

National security, or national defence (national defense in American English), is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, such as the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other states, action by violent non-state actors, by narcotic cartels, organized crime, by multinational corporations, and also the effects of natural disasters.

Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes of insecurity, such as climate change, economic inequality, political exclusion, and nuclear proliferation.

Transnationality is the principle of acting at a geographical scale larger than that of states, so as to take into account the interests of a supranational entity.

Transnational policies or programmes are not simply aggregations of national policies or programmes, but seek to submerge these within a greater whole. According to Aihwa Ong, the term differs from that of transnationalism, as transnationalism refers "to the cultural specificities of global processes, tracing the multiplicity of the uses and conceptions of 'culture'" whereas transnationality is "the condition of cultural interconnectedness and mobility across space".

The Asian diaspora is the diasporic group of Asian people who live outside of the continent. There are several prominent groups within the Asian diaspora.

Asian diasporas have been noted for having an increasingly transnational relationship with their ancestral homelands, especially culturally through the use of digital media.
