question:
Passage: The country's economic transformation was far from complete. Political and financial crises in 1997, shattered the Czech Republic's image as one of the most stable and prosperous of post-Communist states. Delays in enterprise restructuring and failure to develop a well-functioning capital market played major roles in Czech economic troubles, which culminated in a currency crisis in May. The formerly pegged currency was forced into a floating system as investors sold their Korunas faster than the government could buy them. This followed a worldwide trend to divest from developing countries that year. Investors also worried the republic's economic transformation was far from complete. Another complicating factor was the current account deficit, which reached nearly 8% of GDP. In response to the crisis, two austerity packages were introduced later in the spring , which cut government spending by 2.5% of GDP. Growth dropped to 0.3% in 1997, −2.3% in 1998, and −0.5% in 1999. The government established a restructuring agency in 1999 and launched a revitalization program - to spur the sale of firms to foreign companies. Key priorities included accelerating legislative convergence with EU norms, restructuring enterprises, and privatising banks and utilities. The economy, fueled by increased export growth and investment, was expected to recover by 2000.
Question: How many years after the government established a restructuring agency was export growth and investment expect to recover?
answer:
number
