CANBERRA, Nov 3 (Reuters) - Chicago soybean futures edged lower on Friday but were on track for a fourth consecutive weekly gain amid expectations of strong demand from China and worries about the weather in top exporter Brazil.

Corn and wheat prices also dipped.

FUNDAMENTALS

* The most-active soybean contract on the Chicago Board of Trade (CBOT) was down 0.1% at $13.27-1/2 a bushel by 0032 GMT, but up 0.6% this week.

* CBOT wheat fell 0.1% to $5.65 a bushel and was down 1.8% from last Friday's close. Corn slipped 0.2% to $4.69-1/4 a bushel and was down 2.4% over the week.

* China's soybean imports are likely to stay high through the fourth quarter, taking 2023 purchases to an all-time record, analysts and traders said.

* Bolstering hopes for strong exports was news that U.S. agriculture industry representatives met with their Chinese counterparts in Beijing on Thursday to boost farm trade.

* Recent data showed that U.S. soybean meal exports were well on their way to new highs this season after a bad soybean harvest in top soymeal supplier Argentina earlier this year.

* Commodity brokerage StoneX this week lowered its forecast for U.S. soybean production to 4.162 billion bushels from 4.175 billion bushels.

* In Brazil, just months after the country harvested its largest-ever corn and soybean crops, concerns are already brewing over the next crop as wild weather patterns disrupt northern and southern soybean-production areas.

* In Argentina, farmers received 50-60 millimeters (2-2.4 inches) of rain on Thursday, providing relief to the country's thirsty corn crop and an opportunity for farmers to begin sowing soybeans, the Rosario grains exchange said.

* CBOT soybeans have risen around 6% from last month's 22-month low of $12.51, but prices are still down around 13% since the start of the year.

* Moving to wheat, the Buenos Aires grains exchange cut its forecast for Argentina's 2023/24 crop to 15.4 million metric tons from 16.2 million tons, citing adverse weather.

* Ukraine's grain exports rose by 20% to 2.5 million tons in October versus September thanks to a new Black Sea export corridor, the UCAB agricultural business association said, easing supply fears.

* Weekly U.S. export sales data was disappointing, with the government reporting sales of 2023/24 wheat in the week ended Oct. 26 at 275,600 metric tons, below trade expectations for 300,000 to 600,000 tons.

* Commodity funds hold a large net short position in CBOT wheat, leaving the market vulnerable to bouts of short-covering.

* Fund speculators were net buyers of Chicago soybean, wheat and soyoil futures on Thursday and net sellers of corn and soymeal, traders said.
