Question: How did the European Union rank the economy of the country that the Rhine forms a border with, other than the country they filmed scenes with Detlef Bothe?

<P0-S0> the rhine (romansh: rein, german: rhein, french: le rhin, dutch: rijn) is a european river that begins in the swiss canton of graubünden in the southeastern swiss alps, forms part of the swiss-austrian, swiss-liechtenstein border, swiss-german and then the franco-german border, then flows through the rhineland and eventually empties into the north sea in the netherlands. <P0-S1> the biggest city on the river rhine is cologne, germany with a population of more than 1,050,000 people. <P0-S2> it is the second-longest river in central and western europe (after the danube), at about 1,230 km (760 mi),[note 2][note 1] with an average discharge of about 2,900 m3/s (100,000 cu ft/s). <SEP> <P1-S0> The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. <P1-S1> For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita). <P1-S2> In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. <P1-S3> Switzerland also has one of the world's largest account balances as a percentage of GDP. <SEP> <P2-S0> in 2012 the economist intelligence unit ranked warsaw as the 32nd most liveable city in the world. <P2-S1> it was also ranked as one of the most liveable cities in central europe. <P2-S2> today warsaw is considered an "alpha–" global city, a major international tourist destination and a significant cultural, political and economic hub. <P2-S3> warsaw's economy, by a wide variety of industries, is characterised by fmcg manufacturing, metal processing, steel and electronic manufacturing and food processing. <P2-S4> the city is a significant centre of research and development, bpo, ito, as well as of the polish media industry. <P2-S5> the warsaw stock exchange is one of the largest and most important in central and eastern europe. <P2-S6> frontex, the european union agency for external border security, has its headquarters in warsaw. <P2-S7> it has been said that warsaw, together with frankfurt, london, paris and barcelona is one of the cities with the highest number of skyscrapers in the european union. <P2-S8> warsaw has also been called "eastern europe’s chic cultural capital with thriving art and club scenes and serious restaurants". <SEP> <P3-S0> In addition to the principal cast, Alessandro Cremona was cast as Marco Sciarra, Stephanie Sigman was cast as Estrella, and Detlef Bothe was cast as a villain for scenes shot in Austria. <P3-S1> In February 2015 over fifteen hundred extras were hired for the pre-title sequence set in Mexico, though they were duplicated in the film, giving the effect of around ten thousand extras. <SEP> <P4-S0> Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. <P4-S1> The river makes a distinctive turn to the north near Chur. <P4-S2> This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). <P4-S3> Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. <P4-S4> The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East.
