The PGG Wrightson takeover saga has taken another twist, as two Chinese companies appeal to the shareholders of the rural services provider.

Chinese-backed agricultural research firm Agria corporation put a 60c offer to PGG shareholders, which remains the only substantive bid received for the company.

Hong Kong based investment Group Zuellig launched its own bid seeking a 19.9% share in Wrightson, but was soundly rejected by the rural service giant.

PGG Wrightson said in a statement "the approach from Zuellig seems to have a primary motivation of frustrating the Agria offer.

"In the absence of these details and any other material to establish the substance of a potential offer, the independent directors are not able to recommend that PGW shareholders take the possibility of an offer from Zuellig into account when considering their response to the Agria offer." 

Business analyst Brian Gaynor says shareholders should be wary of any offer that doesn’t disclose enough details.

"They're doing a lot of talking, but when there's a takeover offer, you've got to do more than talk, and put your money on the table.

"Nobody's really taking them very seriously.

Zuellig group released a statement on Wednesday saying they are disappointed by Wrightson’s announcement, and they believe they can make a “strong contribution to the company”.

Zuellig reinforced they are still interested in a 19.9% stake in the company despite PGG’s resistance.

PGGW shares finished at 50c on Wednesday, 10c below Agria’s offer.
