Manuel Pangilinan said that Filipino-British company Forum Energy PLC communicated the offer to China National Offshore Oil Corp to explore Reed Bank, northwest of the Philippine island of Palawan. Philippine and Chinese vessels had a confrontation there three years ago.
Pangilinan said the Chinese company, also known as CNOOC, has not responded but Forum is continuing its attempts to engage with the Chinese company. He said the project has not attracted other investors because it is in an area of conflicting territorial claims and other investors did not want to offend China.
He had an initial meeting with CNOOC President Yang Hua in 2012, but the talks have stalled, with the territorial conflict hampering exploration in the area.
Pangilinan said Forum still intends to drill two wells in first half of 2016.

"We will do it on our own if we have to ... As long as we are not disturbed," he said.
The Department of Energy has extended Forum's delayed drilling program by a year, giving it up to Aug 15, 2016 to fulfil its contractual obligations. Pangilinan said weather would permit drilling only from March to May.
President Benigno Aquino III on Tuesday voiced concern that two Chinese hydrographic ships sighted by the military at the disputed Reed Bank in June could presage an attempt to drill for oil there.
In March 2011, Chinese ships tried to drive away a Philippine exploration vessel at the Reed Bank. The Philippines deployed two air force planes but the Chinese patrol ships had left by the time the aircraft reached the contested area.
China and the Philippines, along with Brunei, Malaysia, Taiwan and Vietnam, have been contesting ownership of mostly barren islands, islets, reefs and surrounding waters in the South China Sea for years.
