Can the bidder invite the purchaser to visit the site?

Of course. In the process of bidding, the bidder may invite the purchaser to visit the site, but must abide by the relevant laws and regulations and the provisions of the bidding documents. In China, procurement activities must be carried out in accordance with the Government Procurement Law and other relevant laws and regulations, and buyers and bidders must abide by the provisions of the bidding documents, including the time, place, personnel and methods of inspection. At the same time, the purchaser should also ensure openness and transparency, and other qualified bidders can get equal opportunities for inspection. If the bidder is found to have violated the rules in inviting the purchaser for inspection or other aspects, the purchaser or other bidders may report to the tendering agency or relevant departments.
