Yes, the statement is valid. China’s economic transformation is strongly linked to its effective use of Special Economic Zones (SEZs). Introduced in the early 1980s, SEZs became instrumental in integrating China’s economy with the global market. The following arguments justify this:
Attraction of Foreign Investment: SEZs offered relaxed trade regulations, tax incentives, and infrastructural facilities, which attracted massive inflow of Foreign Direct Investment (FDI), thereby boosting capital formation and industrial growth.
Export-led Growth Strategy: These zones were strategically located near coastal areas to promote export-oriented industries. As a result, China emerged as the ‘world's factory’ and experienced a rapid increase in exports and GDP.
Employment Generation and Technological Advancement: SEZs created millions of jobs and facilitated the adoption of modern production techniques, improving productivity and competitiveness.
Pilot for Economic Reforms: SEZs acted as experimental hubs for broader economic reforms. Successful practices within SEZs were later extended across the country.
Thus, the SEZ strategy transformed China from a closed economy to a global manufacturing giant.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
