Based on my investigation, here is my analysis of the claim:

Reasoning:

• Following the collapse of communism in 1989, Poland underwent a decisive economic transition that included a "definite switch to trade with the West" and market-oriented reforms starting in January 1990¹.
• Poland formally established diplomatic relations with the European Economic Community in 1988 and signed trade and economic cooperation agreements with Western European institutions in 1989, demonstrating an early strategic pivot toward European markets².
• EU accession in 2004 reinforced Poland's market orientation, locking in open markets, competition, and institutional discipline that led to nearly three decades of uninterrupted growth and deep integration into European and global markets³.
• Current trade data confirms this orientation: in 2024, Poland's chief export markets were overwhelmingly European, led by Germany (27.2%), Czechia (6.1%), France (6.1%), the United Kingdom (5.2%), and the Netherlands (4.6%)⁴.
• Poland's exports increased more than 25 times since 1989, and the country has grown faster than all large economies at similar development levels, strongly tied to its integration with European markets⁵.
