There is an economic cooperation among European Union members. Some economic help is given to the poorest or least developed members, which is one of the main reasons or incentive for Eastern European countries, or Turkey, to apply for membership.
The members contributing the most (on a economic viewpoint) are reluctant to stretch even more their obligations towards newcomers. Some countries which are now getting aid from the union, would also become contributors.
Also at stake is the political power within the Union; some new members, like Poland, are eager to get a more favourable position.

The former USSR, headed by Russia, were communist countries. Most of the outlying territories were taken by force and unwillingly converted to communist governments.

Probably, the former USSR and Communist Chinese have litterly "dumped" them onto third world nations (un-developed nations) in order to gain favortism.
In 1998, aging communist leaders of Eastern European nations were largely out of power or facing significant political decline as many countries transitioned to democratic governance and market economies following the fall of the Berlin Wall in 1989. Some former leaders, like those in the Czech Republic and Hungary, were adapting to new political realities, while others were grappling with the legacy of their regimes. The shift towards democracy and integration with Western institutions, such as NATO and the European Union, marked a significant change in the political landscape of the region. Overall, the influence of aging communist leaders diminished as younger, reform-oriented politicians began to emerge.
