�　 are application dependent. The recipient must respond to the Read Message with an　　 Answer Message within the time-out period of 8 seconds. However if a recipient　　 node is unable to respond it must reply with an ACK. If for instance the device was　　 busy it replies with a MSG_ACK of NAK7 or if the Read Message contains an　　 invalid database address the device replies with a MSG_ACK of NAK6.　　 An Answer Message is a message which provides to the originator of a Read　　 Message all the requested data elements.　　 A Write Message is used to send data from an originator to a recipient device. The　　 identifier of the data element is defined in the recipient device. It is possible to write a　　 multiple data elements in the one command. This is achieved by issuing a message　　 including a list of data elements and their values.　　 Sending a Command is considered as writing a data element with no value. The　　 same message is able to send commands and data elements used as parameters.　　 The recipient must respond to the Write Message with an Acknowledge Message　　 within the time-out period of 8 seconds.　　 An Unsolicited Data Message with Acknowledge is used for sending data　　 elements. The recipient must respond to this message with an Acknowl fuel dispenser e fuel dispenser dge　　 Message within the defined time-out of 8 seconds.　　 The only difference from a Write Message is that the data elements (database　　 address data identifier data element contents) are defined in the originator device.　　 An Unsolicited Data Message without Acknowledge is used for sending data　　 elements (e.g. status change error) where the recipient must not respond to the　　 message.　　 The Acknowledge Message is used by the recipient of a mes fuel dispenser

l system gradually becomes more liberal and China becomes an increasingly positive force in the world; •A fast-growing economy, a surge of vengeful nationalism and an attempt by China to displace American power in Asia, regain Taiwan and challenge Japan; •A country in disarray, engulfed by social and political crises as its economy slumps. All are plausible. Much will depend on choices made by China itself and by other powers, especially America. That China does matter is evident from its impact on the global economy. Since 2000, China s contribution to global GDP growth (in purchasing-power-parity terms) has been bigger than America s, and more than half as big again as the combined contribution of India, Brazil and Russia, the three next-largest emerging economies. China s massive build-up of American Treasury bonds affects American interest rates and thus Americans willingness to spend. Its low-priced manufactures give western consumers more buying power. Its thirst for energy has helped push oil prices to record highs. Its entry to the World Trade Organisation in 2001 has speeded up the opening of the world s biggest market. Whereas a few years ago it might not have mattered much to the West if China s growth had faltered, today it would be a very different story. China s growth and increasing confidence is also beginning to affect the way it behaves on the world stage. If only tentatively so far, it is beginni fuel dispenser n fuel dispenser g to act like a big power. A country that once preferred to stay clear of multilateral diplomacy is now at the centre of multilateral efforts to persuade North Korea to abandon its nuclear-weapons programmes. It has formed a club of central Asian powers to deal with security threats. Its secretive armed forces are reaching out to other countries by staging joint manoeuvres (though not yet with the Americans or the Japanese). And China s burgeoning demand for oil and other commodities has made it cosy up to countries whose unsavoury behaviour matters to the West, such fuel dispenser
