Almost a full week after China and the United States signed their historic trade deal paving the way for Beijing's accession to the World Trade Organisation, much of the small print in the pact remains under wraps.
With talks between the European Union and Beijing expected to take place before the end of the month, European embassies in Beijing have still not been briefed on the terms of the accord, say diplomats.
Even mighty corporations like car-maker General Motors say they do not know the full implications of the agreement for their sector. GM is one of the biggest American players in the mainland, with investments of almost US$2 billion.
Only the broad details are being drip fed by US officials, who say they are not ready to release the full document until the EU and others have done a deal.
This is in contrast with the fiasco in April when the US Trade Representative's office published details before they had an agreement. While praising the deal as a breakthrough in the process of reform and Sino-US relations, the mainland media is also keeping quiet on the details.
But EU negotiators do not seem to be in a hurry to talk. A scheduled visit to Beijing on Friday has been deferred.
